ii) Name any one Metalloid.
111) What type of change is cutting of wood.​

Answer 1

SOLUTION

GIVEN

A solution has 50g of salt in 320g of water.

TO DETERMINE

The mass percent of the salt in the solution

EVALUATION

Here it is given that a solution has 50g of salt in 320g of water

So mass of the solution

= 320 g + 50 g

= 370 g

So the required mass percent of the salt in the solution

$\displaystyle \sf{ = \frac{Mass \: of \: the \: salt }{Mass \: of \: the \: solution } \times 100 \%}$

$\displaystyle \sf{ = \frac{50}{370} \times 100 \%}$

$\displaystyle \sf{ = 13.51 \: \%}$

FINAL ANSWER

The mass percent of the salt in the solution

= 13.51%
