Question

a bar of steel has a mass of 277 g and a volume of 35.5 cm3. What is the density of the bar?Will it float in water?Will it float in mercury?

could u please help me with this question?:)

Answer 1

density = mass/volume = 277/35.5 = ??g/cc.If the density is greater than the density of water (1.00 g/cc) it will sink. If it is higher than 1.00 it will sink. Mercury has a density of 13.6 g/cc so steel will ??? in mercury.

Answer 2

density= mass/volume so 277/35.5= 7.8028169 g/cm3...
and water has a density of 1g/cm3 so it will not float in water...
while mercury has a density of 13.6 g/cm3 so it will float in mercury...
I'm in grade 8 but that was easy... ;)
