Question

density of an object is defined as mass per unit volume. mathematically we write that: D =M/V. Rearrange this expression for: (a) M=? (b) V=?

Answer 1

Pressure in the ideal gas law has units of N/m. 2 ... is the number of moles, M is the molar mass and V is the volume.

Answer 2

D =M/V

a) D*V =(M/V)*V

DV = M or M=DV

b) D/1 =M/V

V=(1*M)/D = M/D

V=M/D
