How to Calculate Mass Ratio The following equation demonstrates finding carbon's contribution to CO2: carbon_contribution = 12.01/44.01 * 100 = 27.29% carbon. Solve the equation to get 27.29 percent as carbon's percent contribution to CO2's mass. If you'd rather compute oxygen's mass ratio, solve this equation where 32, or 2 x 16.00, is the mass that oxygen contributes to CO2:

- Definition: density = mass divided by volume; symbol ρ = m / V. ρ (rho) = density, m = mass, V = volume. The SI unit of density is kg/m3. Water of 4 C is the reference ρ = 1000 kg/m3 = 1 kg/dm3 = 1 kg/l or 1 g/cm3 = 1 g/ml.Fill in the appropriate line the known density value. Attention: Do not re-enter the exact number of an answer. kg/dm3 = 1 kg/L = 1000 g/1000 cm3 = 1 g/cm3 = 1 g/ml (water). Water as the reference with its highest density at 3.98 °C is ρ = 1 g/cm3. The correct SI unit is ρ = 1000 kg/m3. 1 m3 = 1,000,000 cm3. Examples: Solid-water-noble gas. Copper has a density of 8950 kg/m3 = 8.95 kg/dm3 = 8.95 g/cm3.

What is the Avogadro Constant? Similarly, as the molecular weight of H2O or water is 18, the mass of one mole of water is 18g. This provides another useful relation, which allows us to calculate the mass of one molecule of a substance. Hence, m = M/NA where M is the molecular mass of a substance, and NA is the Avogadro’s number.

- The following equation describes the reaction between ammonia and water: NH 3 + H 2 O ==> NH 4 + + OH¯ Note that it is an equilibrium condition. The equilibrium constant for this reaction is written as follows: K c = ( [NH 4 +] [OH¯] ) / ( [NH 3] [H 2 O] ) However, in pure liquid water, [H 2 O] is a constant value. To demonstrate this, consider 1000 mL of water with a density of 1.00 g/mL. This 1.00 liter (1000 mL) would weigh 1000 grams. This mass divided by the molecular weight of water (18.0152 g/mol) gives 55.5 moles. The molarity of this water would then be 55.5 mol / 1.00 liter or 55.5 M.
