Question

Calculate the volume ofa 6.0 M HCl(aq) solution that is required to make 250mL of a 1.0 M HCl(aq) solution.

Answer 1

The volume of 6.0 M HCl(aq) solution required = 41.67 mL

Step-by-step explanation:

Considering

`Molarity_(working\ solution)* Volume_(working\ solution)=Molarity_(stock\ solution)* Volume_(stock\ solution)`

Given that:

`Molarity_(working\ solution)=20\ mM=1.0\ M`

`Volume_(working\ solution)=250\ mL`

`Volume_(stock\ solution)=?`

`Molarity_(stock\ solution)=6.0\ M`

So,

`1.0\ M* 250\ mL=6.0\ M* Volume_(stock\ solution)`

`Volume_(stock\ solution)=(1.0* 250)/(6.0)\ mL=41.67\ mL`

The volume of 6.0 M HCl(aq) solution required = 41.67 mL
