Question
What will be the mass of 5 moles of SO2?
- 300 gm
- 330 gm
- 320 gm
- 350 gm
Hint:
Mass of one mole of SO2 is (32 + 2
16) gm = 64 gm.
The correct answer is: 320 gm
Atomic mass of sulfur is 32 gm, atomic mass of oxygen is 16 gm.
Mass of one mole of SO2 is (32 + 216) gm = 64 gm.
Mass of 5 moles of SO2 = (564) gm = 320 gm
