Question

A chemist adds 150.0 mL of a 6.84 g/dL sodium chloride (NaCI) solution to a flask. Calculate the mass in grams of sodium chloride the chemist has added to the flask. Be sure your answer has the correct number of significant digits.

Answer 1

Moles of NaCl $= \frac{150}{1000}× 6.84=1.026mol$

Mass = $1.026× 58.44= 59.96 grams$
