A material with the density of 2.7 grams/mL occupies 35.6 mL. How many grams of the material are there?
Hoochie [10]

Answer:

The mass of material is 96.12 g .

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

Symbol:

The symbol used for density is called rho. It is represented by ρ. However letter D can also be used to represent the density.

Given data:

density of material = 2.7 g/mL

volume= 35.6 mL

mass= ? (in g)

Now we will put the values in the formula,

d= m/v

m=d×v

m= 2.7 g/mL × 35.6 mL

m= 96.12 g

so, the mass of material is 96.12 g .
