The density (ρ) of a substance is its mass per unit volume. Mathematically, density is defined as mass divided by volume [1]: ρ = m/V , where m is the mass, and V is the volume. The SI unit of is kilogram per cubic metre (kg/m3). So, convert cm3 to m3. V = 1547 сm3=0.001547 m3. Then ρ =1.38 kg/0.001547 m3 = 892,0491 kg/m3. Answer rounded to 3 significant figures [2]. Answer: 892 kg/m3
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
