When 2 litres of A is mixed with one litres of B, the density of the mixture is 8 kg/litre
When 1 kg of A is mixed with 1 kg of B, the density of the mixture is 8 kg/litre
Explanation:
Given
Density of liquid A = 6 kg/lt
Density of Liquid B = 12 kg/lt
(1) When 2 litres of A is mixed with one litres of B
Mass of 2 litres of A = Volume x Density = 2 × 6 = 12 kg
Mass of 1 litre of B = 1 × 12 = 12 kg
When the two liquids are mixed, the combined mass = 12 + 12 = 24 kg
The combined volume = 2 + 1 = 3 litres
Therefore, the Density of the mixture
= Mass/Volume
= 24/3
= 8 kg/litre
(2) When 1 kg of A is mixed with 1 kg of B
Combined mass of the mixture = 1 + 1 = 2 kg
Volume of 1 kg of A = Mass/density = 1/6 litre
Volume of 1 kg of B = 1/12 litre
Combined Volume of the mixture
= 1/6 + 1/12 = 3/12 = 1/4 litre
Density of the mixture = Mass/Volume
= 2/(1/4) kg/lt
= 8 kg/litre
Hope this answer is helpful.
