Question

How is mass calculated given density and volume? (1 point) Question 8 options: 1) Volume divided by volume 2) Sum of volume and mass 3) Density multiplied by volume 4) Difference of volume and mass

Answer 1

3) Density multiplied by volume

Step-by-step explanation:

Density:

Density is equal to the mass of substance divided by its volume.

Units:

SI unit of density is Kg/m3.

Other units are given below,

g/cm3, g/mL , kg/L

Formula:

D=m/v

D= density

m=mass

V=volume

So by rearranging this formula mass can be determine.

d = m/v

m = d×/v

Unit of mass when volume in mL and ddensity is g/mL

m = g/mL×mL

m = g

Example:

density = 5g/mL

volume = 3 mL

mass = ?

m = d×v

m = 5g/mL ×3 mL

m = 15 g
