Question

An experiment calls for you to use 100 mL of 0.25 M HNO3 solution. All you have available is a bottle of 3.4 M HNO3. How many milliliters of the 3.4 M HNO3 solution do you need to prepare the desired solution?

Answer 1

Answer: 7.35mL

Step-by-step explanation:

C1 = 3.4M

V1 =?

C2 = 0.25M

V2 = 100mL

C1V1 = C2V2

3.4 x V1 = 0.25 x 100

V1 = (0.25 x 100) /3.4

V1 = 7.35mL
