If 0.38 M of an aqueous solution of magnesium nitrate hexahydrate (Mg(NO3)2 ᐧ 6H2O) was prepared in the laboratory, how many mL of the solution would you need to obtain 4.871 grams of this solute?

50 mL

Explanation:

Given data

We can find the required volume using the following expression.

M = mass of solute / molar mass of solute × liters of solution

liters of solution = mass of solute / molar mass of solute × M

liters of solution = 4.871 g / 256.41 g/mol × 0.38 mol/L

liters of solution = 0.050 L = 50 mL

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
