To determine the composition of a bimetallic alloy, a sample is first weighed in air and then in water. These weights are found to be $w_1$ and $w_2$ respectively. If the densities of the two constituents metals are ${\rho }_1$ and ${\rho }_2$ respectively. then the weight of the first metal in the sample is (where ${\rho }_w$ is the density of water)
