Answer:
0.15M
Explanation:
NaOH + HCl -->NaCl + H2O
moles of NaOH reacted with HCl
(0.5 × 30)/1000 = 1.5 × 10^ -3
so the moles of HCl reacted with NaOH
1.5 × 10^ -3
concentration of HCl = ( 1.5 × 10^ -3)/10 ×1000
If the mass of both the reactants is 10kg then the mass of the products also equals 10kg.
It is due to the law of conservation of mass.
Mass can neither be created nor be destroyed.
