Question

How many moles are present in $6.023\times {10}^{22}$ molecules of $C{O}_2$?

• A. 0.2
• B. 0.01
• C. 0.1
• D. 0.02

Answer 1

Answer: (C)

0.1

1 mole of $C{O}_2$ contains 1 $N_A$ molecules. ( $N_A=6.023\times {10}^{23}$)

Moles present in given sample are: $6.023\times {10}^{22}÷N_A=0.1$
