the relative density of an alloy is 6•5 find the mass of a solid alloy cube of 20cm and what volume of the alloy has a mass of 13kg?

mass = density * volume

so plug in your numbers

Did you know?

Did you know that relative density is a measure of how dense a substance is compared to another substance? In this case, an alloy has a relative density of 6.5, which means it is 6.5 times denser than some reference substance. To find the mass of a solid alloy cube measuring 20cm, we can use the formula: Mass = Density x Volume. Since the relative density is given, we can multiply it by the density of the reference substance to get the density of the alloy (6.5 x density of reference substance). To find the volume of the alloy that has a mass of 13kg, we can rearrange the formula: Volume = Mass / Density. By plugging in the given mass and the density of the alloy (6.5 x density of reference substance), we can determine the volume of the alloy. Understanding relative density and using these formulas allows us to calculate the mass of an alloy and find the volume corresponding to a given mass.
