45g

Step-by-step explanation:

This is a ratio question and we are asked to obtain the mass of the copper.

Firstly, we add both ratios together and thus gives 37 + 3 = 40

Now, we place the ratio of the copper which is 3 and divide by the addition then multiply by the total masses of both in grammes.

Hence we have 3/40 * 600 = 45g

Thus, the mass of the copper in grammes is 45g
