Hello I need help with number 3. 1. An unknown mass of gold displaces 89.1 mL of water in a container. What is the mass of the gold.
-My answer is 1719.63g
2. Using identical conditions, what volume of water will the identical mass of silver displace?
-My answer is 164.2mL
3. Using an identical system, a supposedly gold crown with the same mass is measured and found to displace 138.4 mL. What percent gold is it really? (This is an algebra problem that requires two equations with two unknowns and the answers of questions 1 and 2.)
