How many moles of nacl are found in 2.2 l of a 0.300 m solution?

0.66 moles

Explanation:

Data given:

Volume of the Solution = 2.2 L

Molarity of the Solution = 0.3 M

Number of moles of NaCl = ?

Solution:

To find number of moles of NaCl

Formula used

          Molarity = moles of solute / L of solution

Rearrange the above equation

          moles of solute = Molarity x L of Solution

Put values in above equation

                moles of solute = 0.3 M  x 2.2 L

                moles of solute = 0.66 moles

Moles of NaCl = 0.66 moles

it should be p1 v1 = p2 v2
