Solution

Answer:

Here we have to use dilution law

M1V1=M2V2

1) Given M1=12M, V1=2.48 ml, M2=? And V2=175mL

M1V1=M2V2

(12M) x (2.48 ml)=M2 x (175 ml)

M2=0.17 M.

After diluted to 175 ml the concentration of HCl=0.17 M.

2) Given M1=6M, V1=?, M2=0.336 M and V2=75 ml.

M1V1=M2V2

6M x V1=(0.336 M) x (75 ml)

V1=4.2 ml of stock solution needed to dilute 6M HNo3 to 0.336M.

3) Given M1=3M, V1=3.79 ml, M2=? and V2=175 ml.

M1V1=M2V2

(3M) x (3.79 ml)=M2 x 175 mL

M2=0.0639 M is the diluted solution concentration.
