Question

A sheet of glass has a density of 2.5 g/cm^3.What is the density of the glass in kg/m^3

Answer 1

2.5 g/cm³= 2500 kg/m³

Explanation:

We are given that:

A sheet of glass has a density of 2.5 g/cm^3.

We have to find the density of the glass in kg/m^3

since, 1 kg=1000 g

⇒ 1 g=1/1000 kg

also, 1 m=100 cm

⇒ 1 m×1 m×1 m =100 cm×100 cm×100 cm

⇒ 1 m³= 1000000 cm³

⇒ 1 cm³= 1/1000000 m³

2.5 g/cm³ =
`2.5* (1)/(1000* (1)/(10^6) ) \\\\= 2.5* 10^3` kg/m³

Hence, 2.5 g/cm³= 2500 kg/m³

Answer 2

Easy.Just convert the units one by one.1g=1x10^-3kg

kg and 1 cm^3= 1x10^-6m. So (1x10^-3)/1×10^-6 = 1x10^3.So 2.5gcm^-3=2500kgm^-3
