a piece if magnesium is in the shape of a cylinder with the height of 5.62 cm and diameter of 1.34cm. if the magnesium sample has a mass of 14.1g what is the density if the sample?

Respuesta :

Density  of the sample will be 1.76g/cm³.

What is Density?

Density is the ratio of mass and Volume .The SI unit of Density is g/cm ³or kg/m³.

We have given the height of the cylinder is 5.62cm ,

diameter of the cylinder is 1.34cm

Radius will be 0.67 cm

Volume of cylinder =πr²h

Volume of cylinder= 3.14×0.67×0.67× 5.62

→8cm³(approxapprox)

Density = Mass/ Volume

 Density = 14.1/ 8

density =1.76g/cm³

Hence ,the density is proved .
