Question

How many mega coulombs of positive or negative charge are in 1 mole of neutral molecular hydrogen gas?

Answer 1

Answer:

0.1927 MC

Solution :

Number of hydrogen molecules in 1.00 mole =6.023×1023.

Each molecule has two electrons/two protons

∴n=2×6.023×1023

q=ne=2×0.623×1023×1.6×10−19C

19.27×104C=0.1927MC
