Question

Gelatin has a density of 1.27 g/cm³. If you have a blob of gelatin dessert that fills a 2.0 liter bottle, what is its mass?

A. 2540 g
B. 2500 g
C. 3.9 x 10-4
D. 3.937x 10-4

Answer 1

The answer to this is a. 2,540 g

Answer 2

Answer : Option A) 2540 g

Explanation :

Here, the density of the gelatin is known to be as 1.27
`g/cm^(3)`.

And the volume 2.0 liter

Here, 2 liters = 2
`decimetres^3` so to convert it into
`centimetres^3` we have to multiply it, with 1000 to 2000
`centimetres^3`,

Using, the formula for density;

ρ =
`(m)/(v)`

Here,

ρ = density;

m =mass and v=volume.

Substituting the values given; ρ = 1.27
`g/cm^(3)`

m = to be found and v = 2000
`centimetres^3`

ρ =
`(m)/(2000centimetres^3)`

1.27
`g/cm^(3)` = m X 2000
`centimetres^3`

m = 2540 g

Therefore, the mass will be 2540 g
