Calculation formula of alloy density

Answers on the website:
By definition, density = mass / volume, mass per unit volume
It is known that the alloy is composed of two substances, and the mass is M1 and M2 respectively
If the atomic weights are M1 and M2, the molar ratio is M1 / M1: m2 / m2
In addition, we know the overall volume V and the densities are D1 and D2 respectively
Then v = M1 / D1 + m2 / D2
By solving the above simultaneous equations, M1, M2 can be obtained
It is known that the alloy density = (M1 + m2) / v
You can take the result as a formula
Mine: a long time ago. Is it so troublesome for the high school entrance examination? Just try the mass / volume. No, look at it again
