Step-by-step explanation:

The given data is:

The mass% of a solution is 7.

Mass of solution =450g

The mass of salt required can be calculated as shown below:

$mass percent =(mass of solute/mass of solution )x100\\$

Substitute the given values in this formula to get the mass of solute that is salt:

$mass percent =(mass of solute/mass of solution )x100\\\\7=(mass of salt)/(450g) x100\\=>mass of salt=7x450g /100\\mass of salt=31.5g$

Mass of salt =31.5g

Mass of solvent that is water = 450g-31.5g=418.5g
