1. a.Imagine that there is a certain copper containing metalloprotein, abbreviated R, which contains two copper atoms per molecule of protein. The molar mass of R is 107,000 g/mol. What is the mass % of copper in the metalloprotein?

1.

2.

Explanation:

Hello,

1. In this case, since the volume of the rock is obtained via the difference between the volume of the cylinder with the water and the rock and the volume of the cylinder with the water only:

Thus, the density turns out:

2. In this case, given the density and mass of aluminum we can compute its volume as follows:

Moreover, as the volume is also defined in terms of width, height and length:

The height is computed to be:

Best regards.
