Question

What is the volume of 80.0 g of ether if the density of ether is 0.70g/ml? A) 5.6x10^1 mL B) 1.1x10^2mL C) 8.8x10^-3mL D) 8.0x10^1mL

Answer 1

d- density
m- mass
V- volume
....................
d = m/V
V = m/d
V = 80/0,7 = 114,3mL ≈ 1,1×10^2 mL

B) :•)

Answer 2

Answer : The correct option is, (B)
`1.1* 10^2ml`

Explanation : Given,

Mass of ether = 80.0 g

Density of ether = 0.70 g/ml

Formula used :

`Density=(Mass)/(Volume)`

Now put all the given values in this formula, we get the volume of ether.

`0.70g/ml=(80.0g)/(Volume)`

`Volume=114.285ml\approx 1.1* 10^2ml`

Therefore, the volume of ether is,
`1.1* 10^2ml`
