Question

Harrison is having a tub of yoghurt for a snack. The tub weighs 30g and holds 120ml, so he says that his snack (the tub and yoghurt together ) weighs 150g. Can you please explain why his mistake is mistaken please?

Answer 1

Explanation:

Given

Tub weighs 30 g and can hold 120 ml yogurt

It is not right to simply write the ml to gm unless it is case of water

mass is given by product of volume with density

So, density of yogurt is different than water. It is not appropriate to write 120 ml to 120 gm

Thus, the claim of Harrison is wrong that his snack weighs 150 gm.
