Volume of A used; | 20.50 | 14.00 |14.00 | 14.00 |
Volume of pipette used
=25.00cm³
(1a)
Average volume of A used = 14.00+14.00+14.00/3
=14.00cm³ (Va)
2HNO³ + X²CO³ ---> 2XNO³ + H²O + CO²

Conc - of B in molldm³ = ?
Given;
Ca= 0.15molldm³
Vb= 25.00cm³
Va= 14.00cm³
Cb= ??
Na= 2
Nb= 1
Using;
CaVa/CbVb=Na/Nb
Cb= CaVaNb/VbNa
Cb= 0.15*14.00*1/25.00*2
Cb= 2.1/50
Cb= 0.042molldm³.
(1bii)
Molar mass of B =?
Using;
Conc(molldm³)= Conc(gldm³)/molar mass
0.042/1 * 4.20/m.m
m.m=4.20/0.042
m.m=100glmol
