Question

If 100mL of `1.0M NaOH` solution is diluted to 1.0L, the resulting solution contains
A. 1 mole of `NaOH`
B. `0.1` mole of `NaOH`
C. `10.0` mole of `NaOH`
D. `0.05` mole of `NaOH`

Answer 1

Correct Answer - B
No. of moles `= ((100mL)xx(1mol L^(-1)))/((100mL L^(-1)))`
`= 0.1mol`
`:.` the given solution contains `NaOH = 0.1` mol.
