A NaCl solution of 350 mL volume and a concentration of 0.277 M will contain 5.67 grams of the salt.

Mole calculation

Recall that:

Mole = molarity x volume.

Also:

Mass = mole x molar mass

Hence;

Mole of 350 mL, 0.277 NaCl = 0.350 x 0.277 = 0.097 moles

Mass of 0.097 moles NaCl = 0.097 x 58.44 = 5.67 grams

Thus, a 350 mL, 0.277 M NaCl solution will contain 5.67 grams of the salt.
