Question

can anybody get me the answer I will mark them as brainlest​

Answer 1

Explanation:

Given :-

• Density of first liquid = 2 kg/m³
• Density of second liquid = 3 kg/m³
• Volume of first liquid = 5 litre
• Volume of second liquid = 6 litre

To find :-

Mixed Density of the two liquids.

Solution :-

For first liquid,

density, D1 = 2 kg/m³

volume, V1 = 5 litre = 5 × 10^-3 m³

mass, M1 = density × volume

= 2 × 5 × 10^-3

= 10^-2 kg

For second liquid,

density, D2 = 3 kg/m³

volume, V2 = 6 litre = 6 × 10^-3 m³

mass, M2 = density × volume

= 3 × 6 × 10^-3

= 1.8 × 10^-2 kg

Mixed Density = M1 + M2 / V1 + V2

= 10^-2 + 1.8 × 10^-2 / 5 + 6

= 10^-2 × (1 + 1.8) / 11

= 2.8 × 10^-2 / 11

= 28g / 11 × 10^3 cm³

= 2.545 × 10^-3 g/cm³

or

= 2.545 kg/m³

Hope it helps!
