Questions & Answers

Q: How do you convert moles to grams using molar mass?

To convert moles to grams, you need to identify the molar mass of the substance and use it as a conversion factor in the calculation. Multiply the number of moles by the molar mass to obtain the mass in grams.

Q: What is the molar mass of carbon?

Carbon has an atomic number of six and a mass number of twelve. The molar mass of carbon is 12 grams per mole, meaning one mole of carbon has a mass of 12 grams.

Q: How many grams of sulfur are present in 4.2 moles of sulfur?

Sulfur has an atomic number of 16 and an average atomic mass of 32.07. The molar mass of sulfur is 32.07 grams per mole. By multiplying 4.2 moles by the molar mass, we find that there are 134.694 grams of sulfur.

Q: What is the molar mass of carbon dioxide (CO2)?

Carbon dioxide consists of one carbon atom and two oxygen atoms. The molar mass of carbon dioxide is calculated by adding the atomic mass of carbon (12.01) to twice the atomic mass of oxygen (2 x 16). Therefore, the molar mass of CO2 is 44.01 grams per mole.
