The density of magnesium is 1.7 g/cm³,and the density of iron is 7.9 g/cm³.Consider a block of iron with a mass of 819 g.What is the mass of a block of magnesium that has the same volume as the block of iron?

Question

Quizplus · Accepted Answer

The mass of the magnesium block can be calculated using the formula: mass = density * volume. Since the volume of the magnesium block is the same as that of the iron block, we can use the density of iron to calculate the volume: volume = mass / density = 819 g / 7.9 g/cm³ = 104 cm³. Now we can use the density of magnesium to calculate the mass of the magnesium block: mass = density * volume = 1.7 g/cm³ * 104 cm³ = 176.8 g.
