Question
A sample of hydrogen gas is collected and it is observed that it contains only hydrogen and deuterium atoms in the atomic ratio 6000:1. The number of neutrons in 3.0 g of such a sample should be nearly
Options
A.0.0005
B.3.01 × 1020
C.1.80 × 1024
D.1.0
Solution
Number of neutrons =$\frac{3}{1} \times 6.022 \times 10^{23} \times \frac{1}{6001} = 3.01 \times 10^{20}$
