Question 6
How many atoms are there in 4 moles of carbon? (L = 6.022 × 1023)
The right answer is the one marked above.
2.409 × 1024. 6.022 × 1023 × 4 = 24.088 × 1023 = 2.409 × 1024.
1.506 × 1023 comes from dividing by 4 rather than multiplying. There is more than one mole, so the answer must exceed L.
