Calculate the average atomic mass of hydrogen using the following data
Isotope % Natural abundance Molar mass
`.^(1)H 99.985 1`
`.^(2)H 0.015 2`

A

1

B

`1.00015`

C

2

D

1.5

Text Solution

Verified by Experts

The correct Answer is:
B
Average Atomic Mass
`=(99.985 xx 1 +0.015 xx 2)/(100)`
`=(99.985 + 0.030)/(100) = (100.015)/(100) = 1.00015u`
