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.

Answer:
Explanation:
The surface soil, or topsoil layer (O and A horizon in Figure 1–2), usually contains less clay, but more organic matter and air, than the lower soil layers. Topsoil is usually more fertile than the other layers and has the greatest concentration of plant roots.
Answer:
1.52 M
Explanation:
Molarity of a solution is calculated as follows:
Molarity = number of moles (n) ÷ volume (V)
Based on the information given in this question,
Volume of soda (V) = 9.13 L
number of moles = 13.83 mol
Molarity = 13.83 ÷ 9.13
Molarity = 1.52 M
