Question

Number of hydrogen ions present in 10 million part of 1.3 cm cube of pure water at 25 degree Celsius​

Answer 1

10 million=10-7

so,10 millionth part of 1.33cm3

=1.33*10-7[H+]

=10-7 mol/litre

1000 ml contain 10-7mole

1 ml-----------=10-7/1000 mol 1.33*10-7ml=1.33*10-17

no. of [H+]ions=

1.33*10-17*6.023*10²³ =8.01million
