Question

14. How many moles of sulfur dioxide are in 0.028 g of SO,? What mass of SO, contains exactly 3.000 mol of SO,?

Answer 1

Answer #1

Ans 14

Mass of SO2 = 0.028 g

Moles of SO2 = mass of SO2/molecular weight of SO2

= (0.028 g) / (64 g/mol)

= 0.0004375 mol

= 4.4*10^-4 mol

Moles of SO2 = 3.000 mol

Mass of SO2 = moles x molecular weight

= (3.000 mol) x (64 g/mol)

= 192.0 g
