Question

How many moles of NaCl are found in 2.2 L of a 0.300 M solution?

Answer 1

0.66 moles

Step-by-step 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
