Answer:
The formula mass of NaOH is 40.0 u formula unit. Thus, the molar mass of NaOH is 40.0gmol−1. The required calculation is
Mass→Mole→Litre
0.200gNaOH×1molNaOH40.0gNaOH×1Lsoln0.200molNaOH
=0.025Lsoln
=25mL
We thus need to add 25mL of 0.200MNaOH solution to the reaction vessel.
Alternatively, according to equation 2.14
M=nsoluteVmL×1000mLL
=masssolute(molarmass)soluteVmL×1000mLL
0.200M=0.200gNaOH40.0gNaOHmolNaOH×VmL×1000mLL
orVmL=25mL
