## Homework Statement

an alloy of copper and gold displaces 1.935 cm^3 of water. It has a mass of 33.44g. If gold has a density of 19.3g/cm^3 and copper has a density of 8.9g/cm^3, what is the percent of gold by mass in the object

## Homework Equations

mg=pVg

## The Attempt at a Solution

m alloy= p alloy*V alloy

p alloy = m/V =33.44/1.935 =17.3g/cm^3

i am stuck at this point i found the density of the alloy what do i do next?
