How many liters of a 4.00MNaClsolution will provide25.0g ofNaCl?

Short Answer

Expert verified

0.107mlof a 4.00MNaClsolution provide25.0gofNaCl.

Step by step solution

01

Given information

To calculate how much liters of a4.00MNaClsolution will provide25.0gofNaCl.

02

To calculate the moles of NaCl by using the following expression :

Moles of NaCl=mass ofNaClmolar mass ofNaCl

=25g58.44g/mol

=0.428mol

03

To calculate the volume required by using the following expression :

Volume of NaCl=Moles ofNaClMolarity ofNaCl

=0.428mol4.00M

=0.107L

Therefore, the required volume ofNaClsolution is0.107ml.
