Question

a can weighs 15g when empty, 75g when filled with water, and 76.8g when filled with glycerine.find the relative density of glycerine.
explain it.​

Answer 1

Explanation:

Can When Empty = 15g

Can when Filled with water = 75g

Can When Filled with Glycerine = 76.8g

Mass of Glycerine = 76.8g - 15g = 61.8g

Volume of Glycerine = 15cm³

Density of Glycerine = 61.8g/15cm³ = 4.12g/cm³

Relative Density = Density of Substance/Density of Water

Density of Water = 0.998g/cm³

Rd = 4.12g/cm³/ 0.998g/cm³ =~ 4.12825

HOPE THIS HELPS YOU...

Answer 2

Answer:

1.03

Explanation:

can when empty - 15g

can when filled water - 75 g

can when filled with glycerine - 76.8

mass of glycerine - 76.8g - 15g = 61.8 g

volume of glycerine - 75g - 15g = 60g

density of glycerine - M/V = 61.8/60 = 1.03

Rd of density of glycerine - density of substance/ density of water at 4°C (density of water at 4°C = 1 g/cm³)

1.03 / 1 = 1.03
