Answer 1

see this and solve yourself to get answer..

Answer 2

Dear friend,

● Answer -
Molarity = 0.58 mol/L

● Explaination -
Moles of solute is calculated by -
n = 5.5 / 36.5
n = 0.1507 moles

Volume of solution is given by -
Volume = mass / density
Volume = (200 + 5.5) / 0.79
Volume = 260 ml = 0.26 L


Molarity of the solution is calculated by -
Molarity = moles of solute / volume of solution
Molarity = 0.1507 / 0.26
Molarity = 0.58 mol/L

Hence, molarity of the soln ia 0.58 M.

Hope this helps you..
