1.	I) A solution has 50g of salt in 320g of water. Calculate the mass percent of the salt in thesolution. ii) Name any one Metalloid. iii) What type of change is cutting of wood.
Answer» ANSWER: Evaluation here it is given that a SOLUTION has 50G of salt in320g of water so MASS of the solution =320g+50g =370g so the required mass percent of the salt in the solution =mass of the salt÷mass of the solution ×100% =50÷370×100% =13.51%

I) A solution has 50g of salt in 320g of water. Calculate the mass percent of the salt in thesolution. ii) Name any one Metalloid. iii) What type of change is cutting of wood.

Answer»

Evaluation

here it is given that a SOLUTION has 50G of salt in320g of water

so MASS of the solution

=320g+50g

=370g

so the required mass percent of the salt in the solution

=mass of the salt÷mass of the solution ×100%

=50÷370×100%

=13.51%
