Good morning and welcome to Chemistry. Happy April. Sigh.

Today’s questions continue with moles, Avogadro’s number, and molar mass.

Remember: 1 mole Ca = 6.02 x 10²³ atoms Ca = 40.078 g Ca (molar mass of Ca)

1. How many atoms of Ca is 1.00 grams of Ca?
2. What is the mass of 1 atom of Ca?

Do the work on paper. Both are two-step problems. Does your answer make sense (so, for example, one atom of Ca does NOT equal 40 grams.)

Good luck.

Stay Healthy and Stay Breezy!
