How many mega coulombs of positive(or negative) Charge are present in `2.0 mol` of neutral hydrogen gas.

Text Solution

Verified by Experts

The correct Answer is:
0.1927 MC
Number of hydrogen molecules in 1.00 mole `= 6.023xx10^(23)`.
Each molecule has two `"electrons"//"two protons"`
`:. n = 2xx6.023xx10^(23)`
`q =n e = 2xx0.623xx10^(23)xx1.6xx10^(-19)C`
`19.27xx10^(4) C = 0.1927 MC`
