A chemist adds of a barium chloride solution to a flask. Calculate the mass in grams of barium chloride the chemist has added to the flask. Be sure your answer has the correct number of significant digits.

The question is incomplete, here is the complete question:

A chemist adds 50.0 mL of a 0.277 M barium chloride solution to a flask. Calculate the mass in grams of barium chloride the chemist has added to the flask. Be sure your answer has the correct number of significant digits.

The mass of barium chloride is 2.88 grams

Explanation:

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

Given mass of barium chloride = ? g

Molar mass of barium chloride = 208 g/mol

Molarity of solution = 0.277 M

Volume of solution = 50.0 mL

Putting values in above equation, we get:

Hence, the mass of barium chloride is 2.88 grams
