How many grams of magnesium sulfate are in 2ml of a 50 percent magnesium sulfate solution?

Answer 1

To calculate the grams of magnesium sulfate in a solution, we need to know the density of the solution. However, assuming it is a water-based solution, we can estimate the mass by using the percent composition.

A 50% solution means that 50% of the solution is magnesium sulfate. This can be expressed as a ratio of 50/100 or 0.5.

Since 1 mL of water has a density of approximately 1 g/mL, we can assume that the density of the solution is also 1 g/mL.

So, for a 2 mL solution, the mass of the solution would be 2 g.

Since the solution is 50% magnesium sulfate, multiplying the mass of the solution by 0.5 will give us the mass of magnesium sulfate in the solution:

Mass of magnesium sulfate = 2 g × 0.5 = 1 g

Therefore, there are 1 gram of magnesium sulfate in 2 mL of a 50% magnesium sulfate solution.
