Concentration is how many moles there are per unit volume, therefore, find the quantity of substance:
n=CV. The mass is the product of molar mass and n:
m=nM=CVM==0.1(23.7⋅10−3)(1⋅2+32+16⋅4)=0.232 g.
The pH is the negative decimal logarithm of hydrogen ion concentration in the solution. The sulphuric acid dissociates into two ions, both of the same and equal concentration of 0.100 M:
H2SO4=H++HSO4−,pH=−lg[H+]=−lg[0.100]=1.
