Question

What is the concentration, in g/mL, of a solution made by dissolving 75.0 g of phosphoric acid in 50.0 mL of solution?

Answer 1

What is the concentration, in g/mL, of a solution made by dissolving 75.0 g of phosphoric acid in 50.0 mL of solution?

Concentration can be calculated as mass (g) divided by volume (mL):

$$C = \frac{m}{V}$$ $$C = 75 / 50 = 1.5 \ \mathrm{g/mL}$$ $$C = 1.5 \ \mathrm{g/mL}$$
