Question

how to solve the above question ​

Answer 1

Answer:

84.2 + 36+60 =94.8 please mark me as brilliant answer

Answer 2

●Given that :

• Mass of Solid : 84.2grams

• Initial volume of water in the cylinder : 36 mL →vu(let)

• Final volume of water in the cylinder : 60 mL→vv(let)

→vu - vv = V

60mL - 36mL = 24 mL

●To Find :

•The density of the solid= ρ

●Solution :

$\: \: \: \: \: \: \: \: \: \: \: \: \red{\bold {density = \frac{mass}{volume} }} \\ \\ \sf \: ρ = \frac{m}{V} \\ \\ \sfρ = \frac{84.2g}{24mL} \\\ \\ \sf ρ= 3.5 g {mL}^{ - 3}$

●Key Points :

• The density of a substance is it's mass per unit volume

•The formula for density : ρ = m/V

here;

'ρ(rho)' a Greek word used as symbol for density.

'm' is the mass of the substance

'V 'is the volume of the substance.

• Density is directly proportional to mass.

• density is inversely proportional to volume.

I hope you understand.
