PLEASE SHOW WORK!!!! Given the density of iron is 7.9 g/cm3 , what would be the volume of a 3.56 g piece of iron?

Answer 1

Here we go,

Density= mass/volume or d=m/V. so to get the volume of iron we have to rearrange the equation for V. We multiply each side by the volume and divide by the density and we get V=m/d.

V=3.56g/(7.9g/cm³). Grams cancel out and we're left with cm³ which is the same as mL.
