An alloy contains 40% by mass of lead and 60% by mass of tin. Determine the density of the alloy in kgm^3. (Density of lead = 1.4g/cm^3 and density of tin = 7.3g/cm^3)​

The density of the alloy is 8.94 g/cm³

Density

Density of a substance is defined as the ratio of its mass and volume.

Formula for density is:

  • Density = mass/volume

Alloy

An alloy is a mixture of two or more metals

Density of the alloy

  • Density of the alloy =  Mass fraction of lead * density of lead + Mass fraction of tin * density of tin

From the data provided:

mass fraction of lead = 0.4

density of lead = 11.4 g/cm³

mass fraction of tin = 0.6

density of tin = 7.3g g/cm³

Density of alloy = 0.4 * 11.4 + 0.6 * 7.3

Density of alloy = 8.94 g/cm³

Therefore, the density of the alloy is 8.94 g/cm³
