Question

you are given 450.0g of s 0.7500 molar solution of acetone dissolved in water. how many grams of acetone in this solution?

Answer 1

Answer:

Explanation:

Molar mass acetone = 58,08 g/mol

Mass of 0.7500 mol acetone = 0.7500 mol * 58.08 g/mol = 43.56 g

To make 0. 7500 m solution of acetone : 43.56 g in 1.0 L or 1000 g H2O

Total mass = 1043.56 g

grams acetone in 450 g solution = 450 g / 1043.56 g

Answer 2

Explanation:

Molar mass acetone = 58,08 g/mol

Mass of 0.7500 mol acetone = 0.7500 mol * 58.08 g/mol = 43.56 g

To make 0. 7500 m solution of acetone : 43.56 g in 1.0 L or 1000 g H2O

Total mass = 1043.56 g

grams acetone in 450 g solution = 450 g / 1043.56 g * 43.56 = 18.78 g
