How do you get the atomic weight of brass?

Answer 1

Brass does not have an atomic weight as it is an alloy. An alloy consisting of Copper (Atomic Weight: 63.546) & Zinc (Atomic Weight:65.38). This is why there is no Atomic Weight available for it. Once in a while a comparison of metals requires commonality. Such as if you were comparing the mass of a Brass item to say one of Lead (Atomic Weight:207.2). Mixtures of Brass vary from 5% Zinc to 45%. As you can easily see the weight of both Copper and Zinc are close in weight, and both are about 1/3 of the Lead. This would mean that if you were making a weight for say "skin diving" if you used lead instead of Brass the lead would be 1/3 the size and identical weight.

I hope this had helped you.

Answer 2

The atomic weight of brass is calculated by finding the weighted average of the atomic weights of its constituent elements, copper and zinc. This can be done by multiplying the atomic weight of each element by its respective percentage in the brass alloy and then adding the results together.
