http://api.3m.com/how+to+determine+molar+mass+of+a+gas WebGenerally, the molar mass is the ratio of the mass of a substance to the number of particles it contains. It can be calculated by adding the standard atomic mass of its constituent atoms. Molar Mass Formula: A mole is a counting unit used to determine the number of molecules, atoms, ions, or molecular formula units in a certain compound.

molecular mass = (1 x 14.0067) + (3 x 1.00794) molecular mass = 14.0067 + 3.02382 molecular mass = 17.0305 Note the calculator will give an answer of 17.03052, but the reported answer contains fewer significant figures because there are six significant digits in the atomic mass values used in the calculation. Meer weergeven For example, to find the molecular mass of NH3, the first step is to look up the atomic masses of nitrogen (N) and hydrogen (H). H = 1.00794 … Meer weergeven Here's a more complicated example: Find the molecular mass (molecular weight) of Ca3(PO4)2. From the periodic table, the atomic … Meer weergeven WebThe molar mass is calculated by measuring the mass and the number of moles in a sample of the substance of interest, and then dividing both amounts: Where m is the mass, n the number of moles and M the resulting molar mass.

WebTo calculate the relative molecular mass of slaked lime, Ca (OH)2, we need to add up the atomic masses of its constituent atoms. The atomic mass of calcium (Ca) is 40.08, the atomic mass of oxygen (O) is 16.00, and the atomic mass of hydrogen (H) is 1.01. So, the relative molecular mass of slaked lime is: Ca (OH)2 = (40.08) + 2 (1.01 + 16.00 ...
