The mass of magnesium, which has a density of 1.74 g/cm is 504.6 g.

<h3>What is mass?</h3>

Mass is the quantity of matter. Mass can be calculated by multiplying density by volume.

Magnesium is a chemical element with the atomic number 12. It is needed in the body in trace amounts. It can cause malnutrition in the body.

Mass = Density x volume

We know the density and the volume of magnesium.

Density = 1.74

Volume = 290

Density x volume

Putting the value in the equation

1.74 x 290 = 504.6 g

Thus, the mass of magnesium is 504.6 g.
