What is the density of a substance of mass 100 g and volume 10cm3 ?
Mass = 100g Volume = 10 cm³ Density = Mass/Volume = 100/10 = 10 g/cm3
The volume of 100g of a substance is 20cm3. If the density of water is 1 gcm−3, the substance will sink.
The mass per unit volume of a substance is called density (density = mass/volume). Arrange the following in order of increasing density − air, exhaust from chimney, honey, water, chalk, cotton, and iron.
