- 1 Answer 1. So we are assuming that Aluminium is a sphere. Notice that $Density=\frac {mass}{Volume}$. Also notice that the atomic mass given is for one mole of Aluminium. Therefore, you must convert the mass to a single atom (use mole). The Volume is $Volume=\frac{mass}{Density}$ and the Volume of a sphere is $Volume=\frac{4}{3}\pi r^3$.

- (a) Compare the total mass of these asteroids to the mass of Earth. (b) Assuming a spherical shape and a density of rho, estimate the diameter of an asteroid ANSWER: The total mass of all asteroids would be 20,000 10 17 21kg = 2 10 kg.s we see them today, the asteroids would not make up much of a planet! A single body would have the following size. Use the formula for density: 317 (4/3)5103000  R = 20,000 m or 20 km, so the diameter would be 40 km.

mass (m) where F is the applied force in newton s, m is the mass of the object or particle in kilograms, and a is the resulting acceleration in meters per second squared. The mass of an object can be calculated if the force and the acceleration are known. Mass is not the same thing as weight. Weight has meaning only when an object having a specific mass is placed in an acceleration field, such as the gravitational field of the earth.

How to Calculate the Weight of Angle Iron Take the dimensions of the tall portion of the L. Calculate the weight by multiplying the width times the length times the height and then multiplying the resulting volume by 0.259. Add these two weights to get the total weight of the angle iron. If you counted the corner intersection of the long and short parts of the L twice, you'll need to find its weight and subtract that from your final result.

What is the mass of two moles of NaCl? In order to find the mass of x moles of any substance, one must first determine the substance's molar mass. For atoms, molecules, etc. the molar mass is equal to the atomic weight (or sum of atomic weights, in the case of molecules) in grams. This can be proved by the following: (X amu/type of item) x (1.66x10^-24 grams/ 1 amu) x (6.02x10^23 items/ 1 mole) =.

- 3.09%. Therefore, the atomic weight of silicon is. (27.977)(0.9221) + (28.976)(0.0470) + (29.974)(0.0309). = 28.086 amu. It is important to note that if we were to pick out a silicon atom at random and measure its mass, it would have a mass of either 27.977 amu, 28.976 amu or 29.974 amu, not 28.086 amu.owever, if you were to measure the masses of a billion silicon atoms (a quantity probably to tiny to see with the naked eye) individually and calculate the average mass you would find the average mass of a silicon atom is 28.086 amu. Molecular Weight.

- Molar mass is computed as the sum of the masses of all elements in the compound considering one mole of that substance. The mass of Ca is 40.08 amu while the mass of I2 is 126.9 amu. In the equation, there are 1 unit of Ca and 2 units of I2. Thus, (1 Ca x 40.08 amu) + (2 I2 x 126.9 amu) is equal to 293.88 amu.

CONTENTS The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams. The same concept can be extended to ionic compounds and molecules. One formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu for Na + 35.453 amu for Cl), so a mole of sodium chloride would weigh 58.44 grams.

How to Calculate Percent Error You measure the dimensions of the block and its displacement in a container of a known volume of water. You calculate the density of the block of aluminum to be 2.68 g/cm 3. You look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm 3. Calculate the percent error of your measurement.1  Subtract one value from the other: 2  2.68 - 2.70 = -0.02. 3  Depending on what you need, you may discard any negative sign (take the absolute value): 0.02. 4  This is the error.ou look up the density of a block aluminum at room temperature and find it to be 2.70 g/cm 3.

What is the mass of aluminium in 204 g of aluminium oxide? If we make the balanced equation between al giving al2o3, The number of aluminum atoms is two and the number of oxygen atoms is three. As we know the atomic masses of aluminum as 26.9815386 grams per mole and oxygen as 16.9994 grams per mole. Multiplying the number of atoms of each of these elements by its respective atomic weight and then adding them, the molecular weight of Al2O3 is 101.961276 grams per mole.

Atomic mass From Wikipedia, the free encyclopedia. An atomic mass (symbol: m a) is the mass of a single atom of a chemical element. It includes the masses of the 3 subatomic particles that make up an atom: protons, neutrons and electrons. Atomic mass can be expressed in grams. However, because individual atoms have very small masses, this is not very helpful.
