Question

6 jam jars of volume 0.37 m3 are filled with jam. An empty jam jar has a weight 200g each. the weight of all 6 jars filled with jam is 5400g. Calculate the density of jam using this information.

Answer 1

Answer:

Density of jam = 11.35 kg/m³

Explanation:

1- Getting the mass of the jam:

We are given that:

Jam is put in 6 jars

the weight of one empty jar = 200 grams

Therefore:

weight of 6 empty jars = 6 * 200 = 1200 grams

We are also given that:

Weight of all jars filled with jam is 5400 grams

Therefore:

mass of jam = total mass of jam and jars - mass of 6 empty jars

mass of jam = 5400 - 1200

mass of jam = 4200 grams

2- Getting the volume of the jam:

We are given that the 6 jars had a total volume of 0.37 m³ and that they were completely filled with jam

This means that:

Volume of jam = 0.37 m³

3- Getting the density of jam:

Density can be calculated using the following rule:

$Density = \frac{mass}{volume}$

We have:

Mass of jam = 4200 grams = 4.2 Kg

Volume of jam = 0.37 m³

Therefore:

$Density = \frac{4.2}{0.37} = 11.35 kg/m^3$

Hope this helps :)
