Calculate the mass percent of each element in CaCO3?
CaCO3 is the formula of the substance (calcium carbonate), which gives the information about the proportions of the different elements which make up the compound. To find the 'mass percentage' however, it is necessary to use the molar mass of each element. Molar mass of Calcium = 40.08 g/mol Molar mass of Carbon = 12.01 g/mol Molar mass of Oxygen = 16.00 g/mol To find the percentage mass of one of these elements, divide the molar mass of the element by the total molar mass of the compound (add them all up, using oxygen three times), then multiply by 100%. Molar mass of CaCO3 = 40.08 +12.01 + 3*16.00 = 100.09 g/mol % Calcium = 40.08/100.09 * 100% = 40.0% % Carbon = 12.01/100.09 * 100% = 12.0% % Oxygen = (3*16.00)/10.09 * 100% = 48.0%
What is the molar mass of PH3?
The molar mass of PH3, which is the chemical formula for phosphine, can be calculated by adding up the atomic masses of the elements in the compound. Phosphorus (P) has an atomic mass of approximately 30.97 g/mol, while hydrogen (H) has an atomic mass of approximately 1.01 g/mol. Therefore, the molar mass of PH3 is approximately 30.97 + (3 * 1.01) = 33.00 g/mol.
Would you expect the particles in chlorine gas to diffuse faster or slower than the particles in argon gas?
The rate of diffusion of a gas depends on the weight of the gas molecules. The heavier the molecules, the slower they move - the lighter the molecules, the faster they move. Nitrogen molecules weigh about 28 units. Chlorine molecules weigh 71 units. So we would expect nitrogen to diffuse more quickly than chlorine.
How many molecules of BH3 are in 14.32 grams BH3?

What is the mass of 0.500 mol of NH3?
NH3, or ammonia, has a molar mass of 17.031 g/mol. So .500 moles of the substance would equal 8.5155 grams.
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
What is the molar mass of the sugar called glucose?

The molar mass of C3H8O2 is?
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
What is molar mass of iron?
The molar mass of iron is 55.845g per mol. Molar mass is the mass of a given substance divided by its amount of substance.
How can one determine the molar mass from molality?
To determine the molar mass from molality, you can use the formula: Molar mass (molality x molar mass of solvent) / molality of solute. This equation helps you calculate the molar mass of a substance based on its molality in a solution.
What is the molar mass of Klonopin?
The molar mass of Klonopin is 315,715 g.
What is the molar mass of lithium oxide Li2O?
Lithium has a molar mass of 6.94 g/mol. Oxygen has a molar mass of 16.00 g/mol. Since Lithium Oxide has 2 Lithium atoms, the molar mass is: (6.94 x 2) + 16.00 = 29.88 g/mol.
How do you find the percent of oxygen by mass in a compound?
To find the percent of oxygen by mass in a compound, you need to know the molar mass of the compound and the molar mass of oxygen. Divide the molar mass of oxygen by the molar mass of the compound and multiply by 100 to get the percentage.
Which term is used to represent the mass of 1 mole of molecules of a substance?
This is equal to the molar mass of this substance.
