Answer:2.7 Litres
Explanation:
Decinormal solution means the normality of solution is N/10
300 mL(0.3 litre) of N/10 HCL is present
Normality= no.ofgramequivalent/Volume
No. of gram equivalent of HCL= 0.3*0.1= 0.03
let the amount of water to be added be X Litres
New volume of water= (0.3+X) Litres
By the equation
0.01= 0.03/(X+0.3)
=> 1/3=1/(X+0.3)
=>3=X+0.3
=>X=2.7
volume of water to be added= X= 2.7L litres
