How many times is the mass of a piece of marble with a volume of 1m3 greater than the mass of a piece of paraffin of the same volume?
To find the ratio of the masses of pieces of marble and paraffin, we use the formula: k = mm / mp = ρm * V / (ρp * V) = ρm / ρp.
Constants: ρm – density of marble (according to the condition ρm = 2700 kg / m3); ρп is the density of paraffin (according to the condition ρп = 900 kg / m3).
Let’s make a calculation: k = ρm / ρp = 2700/900 = 3 p.
Answer: The mass of a piece of marble is 3 times more.
