Answer: -

0.2 moles of NaCl are contained in 100.0 mL of a 2.0 M solution

Explanation: -

Strength of NaCl = 2.0 M

Volume of NaCl solution = 100.0 mL

= [tex] \frac{100}{1000} [/tex]

= 0.1 L

Number of moles of NaCl = volume of NaCl x Strength of NaCl

= 0.1 L x 2.0 M

= 0.2 moles

0.2 moles of NaCl are contained in 100.0 mL of a 2.0 M solution
