Question

11. The mass of an empty density bottle is 30 g, it
75 g when filled completely with water and 65.
when filled completely with a liquid. Find :
(a) volume of density bottle,
(b) density of liquid, and
(c) relative density of liquid.
Ans: (a) 45 mL (b) 0.77 g cm (c) 0-71​

Answer 1

Explanation:

given the mass of empty density bottle =30 g and 75g when filled completely with water and 65g filled completely with a liquid volume=75 g-30g = 45g=45ml ,since 1 cubic metre=1000 litre and density of liquid=density of liquid /density of water=65-30/75-30=35/45 =0.77 g per cubic centimetre
