What is the mass of 9.38*10^24 molecules of methanol?

first what's the mass of 1 mole of CH3OH

C = 12

H3 = 3x1 = 3

O = 16

H = 1

Total 32g So we know 6.02x10^23 molecules weigh 32g

1 molecule weighs 32/6.02x10^23 g so 9.38*10^24 molecules weighs

9.38x10^24 x (32/6.02x10^23 = 505g (to 3 sig figs
