Question

caustic soda solution is found to be 60% by mass and 1.6 g/ml density how much water to be added for 7.2 L for M/2 solution​

Answer 1

Answer:

volume of water must be added is 4.32L

Explanation:

number of moles(n)=molarity×molar mass

(n)=0.5M×40g/mol

=20mol

therefore

if 20mol available 7.2L

60%of 20mol ?

then

7.2Lx12mol/20mol

=4.32L must added
