The question is incomplete, complete question is :

A chemist adds 55.0 mL of a 1.1 M barium acetate solution to a flask. Calculate the mass in grams of barium acetate the chemist has added to the flask. Be sure your answer has the correct number of significant digits.

15.4 grams is the mass of barium acetate the chemist has added to the flask.

Explanation:

Mass of barium acetate = x

Molar mass of barium acetate = 255 g/mol

Volume of solution = 55.0 mL = 0.055 L ( 1 mL = 0.001 L)

Molarity of the barium acetate solution = 1.1 M

15.4 grams is the mass of barium acetate the chemist has added to the flask.
