Question

Material A has a density of 4.5g/cm³.

Material B has a density of 14g/cm³.

5kg of Material A and 200g of Material B form Material C.

Work out the density of Material C.

Answer 1

Answer:

Given-

• Material A has density 4.5g/cm^3
• Material B has density 14g/cm^3

• Mass of Material A is 5kg
• Mass of Material B is 200 grams

To Find-

• The density of Material C

Formulae Used-

• Density=Mass/ Volume

Solution-

• Density of Material A = Mass/ Volume

4.5g/cm^3=5kg/Volume

0.9×1/10cm^3=Volume

Volume= 0.09cm^3

• Density of Material B= Mass/Volume

200 = 14g/cm^3/Volume

Volume=14.28cm^3

As per question-

• It was said that Material C Density was formed by the Density of Material A and B. So the Mass will be also formed by the Material A and B

• Density= Mass/Volume

5200g/14.37cm^3

361.864g/cm^3
