Number of hydrogen ions present in 10 millionth part of `1.33 cm^(3)` of pure water at `25^(@)C` is

A

6.023 million

B

60 million

C

8.01 million

D

80.23 million

Text Solution

Verified by Experts

The correct Answer is:
C
A mole contains `6.022 xx 10^(23)` ions
Concentration of free `H^(+)` ions.
Volume of water `= (1.33)/(10^(3)) L xx (1)/(10000000)`
So.no. of hydrogen ions ` = (1.33)/(10^(3) xx 10^(7)) xx 6.022 xx 10^(23) xx 10^(-7)`
= 8.01 million.
