Answer: The grams of solute required to make 250 g of 0.10% MgSO_4 is 0.25 g

Explanation:

To calculate the mass percent of element in a given compound, we use the formula:

\text{Mass percent}=\frac{\text{Mass of solute}}{\text{Mass of solution}}\times 100

Given :

Mass of solution = 250 g

Mass percent of solution = 0.10%

Putting in the values:

0.10=\frac{\text{Mass of solute}}{250g}\times 100

{\text{Mass of solute}}=0.25g

Answer:

= 0.25 g MgSO4

Explanation:

0.10% implies that the solution will contain 0.1 g of magnesium sulfate, for every 100 mL of solution.

Therefore;

= 250 g × 0.1 g/100 mL

= 0.25 g MgSO4

What do the subscripts mean in a molecular formula ?​
horsena [70]

Answer:

A molecular formula tells us what atoms and how many of each type of atom are present in a molecule.

Explanation:

If only one atom of a specific type is present, no subscript is used.

For atoms that have two or more present, a subscript is written after the symbol for that atom.

Molecular formulas do not indicate how the atoms are arranged in the molecule.
