Question

How many milliliters of a 1M nitric acid solution are required to prepare 60mL of 6.7M solution?

A) 400 mL
B) 4mL
C) 0.25 mL
D) none of the above

Answer 1

the number of milliliters of a 1M is 402mL

Step-by-step explanation:

The computation of the number of milliliters could be determined by using the following formula

As we know that

`V_1* M_1 = V_2* M_2`

where,

V_1 and V_2 are the starting and final volumes

And, the M_1 and M_2 are the starting and the final molarities

Now the V_1 is

`V_1 * 1M = 60mL * 6.7M`

So, the V_1 is 402mL

Hence, the number of milliliters of a 1M is 402mL
