9.02 moles of pure R-11

Question

If an air conditioning compressor contains 9.02 moles of pure R-11 (CCl3​F), how many grams of R-11 are in the compressor?

Options

3.95 X 10^22

1.09 X 10^3

1.24 X 10^3

2.06 X 10^-21

6.57 X 10^-2

4.55 X 10^2

7.46 X 10^26

6.57 X 10^26

Answer 1

molar mass CCl3F = 137.37 g

9.02 moles x 137.37 g/mole = 1239 g = 1.24x10³ g
