Question

material A has a density of 4.5g/cm^3 material B has a density pf 14g/cm^3 5kg of material A and 200g of material B form material C work out the density of material C

Answer 1

the density of material C is 0.00462 kg/cm^3.

Explanation:

The total volume of material C will be the sum of the volumes of material A and material B:

Total volume of material C = Volume of material A + Volume of material B

Total volume of material C = 1111.11 cm^3 + 14.29 cm^3

Total volume of material C = 1125.40 cm^3 (rounded to 2 decimal places)Now we can calculate the density of material C by dividing the total mass of the mixture (5 kg + 200 g = 5.2 kg) by the total volume of the mixture:Density of material C = Total mass / Total volume

Density of material C = 5.2 kg / 1125.40 cm^3

Density of material C = 0.00462 kg/cm^3 (rounded to 5 decimal places)Therefore, the density of material C is 0.00462 kg/cm^3.

Answer 2

• 4.62 g/cm³

------------------------

• Density = Mass/ Volume
• d = m/v

Mass of material C is:

• m = 5 kg + 200 g = 5000 g + 200 g = 5200 g

Volume of material C is:

• v = 5000/4.5 cm³ + 200/14 cm³ = 1125.39 cm³

Find the density of material C:

• d = 5200/1125.39 = 4.62 g/cm³
