Question

Question 4 1 pts 15.3 g of magnesium oxide makes up 33.5% of a solution. What is the mass of the solution?

Answer 1

Solution Let the total volume of the solution be v letres Now, According to the question, 33.5 *V = 15. 32 10 3 kg T 100 T - - V= 15.3 x/0-3 x 100 = 0.0456 litres 33.5 V= 45.6 me Total volume of the solution = 45.6 ml of solution. I 33.5% of volume = 15.27 me of solution 15.27 md of solution has a mass o= 15.3 g of Mg o- ime of solution has a mass = 15.39 15.27 . .: 1 : 45.8ml of solution has moss - 15.3 x 45.69 = 45.689 grams of Mgo 15.27
