45.0 g of CaCl are dissolved in enough water so that the molarity of the solution is 1.15 M. What is the volume in mL of the solution?

Answer 1

I'm guessing the chemical formula is actually CaCl₂, which has a molar mass of 110.98 g/mol. We need to go from grams to moles, then using our molarity and moles, determine volume.

45.0 g CaCl₂ (1 mol CaCl₂ / 110.98 g CaCl₂) = 0.405 mol CaCl₂

0.405 mol CaCl₂ (1 L solution / 1.15 mol CaCl₂) = 0.353 L solution

0.353 L solution (1000 mL / 1 L) = 353 mL solution
