To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...
You can look up atomic masses in the periodic table, and you can calculate the molecular mass of a compound based on its chemical formula. Once you know the atomic mass of a compound, you immediately know the mass of a mole of that compound (molar mass). If you have a sample of the...
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles. When dividing by two units that both use grams in their measurement ...
What is atomic mass and how to measure the atomic mass of a proton? Atomic mass refers to the weight of subatomic particles (Electron, Neutron, and proton). Learn more about Atoms and Molecules here in detail. Ways to Calculate the Mass of Proton There are three ways to find the mass ...

# of moles= mass of the gas/molecular mass The Attempt at a Solution I converted Liters to grams, which would make it 7,710 grams, but I'm not sure how to find the molecular mass of the gas, when just given the temperature and the pressure. Physics news on Phys....
Review how to calculate the mass of a liquid from its volume and density. Density is mass per unit volume: density = mass / volume You can rewrite the equation to solve for mass: mass = volume x density Densityof liquids usually is expressed in units of g/ml. If you know the density...
Calculate the amount of the component in moles using the formula, Amount (in moles) =mass (compound)/molecular mass (compound). In our example, Amount (NaOH)=0.5 g /40 g/mole= 0.0125 moles. Step 3 Convert moles to millimolesusing the following proportion: 1 mole corresponds to 1 milli...
