Video transcript

Hi everyone here, we have a question telling us that a solution was prepared by dissolving 15.5 g of potassium oxalate and 550 g of water, determine the percent by mass of potassium oxalate in the solution so our percent mass equals the mass of the component, divided by the mass of the solution times 100. So we have a percent mass equals 15 0.5 g of potassium oxalate, divided by 15.5 g a potassium oxalate Plus 550 grams of water times And that equals 2.74%. And that is our final answer. Thank you for watching. Bye.
