Question

5.85gNaClis dissolved in 500ml of water. the molarity is​

Answer 1

Answer:

0.2 M

Explanation:

Molar mass of NaCl=58.5

500ml = 0.5 L

Molarity = moles of solute / volume of solution in litres

              = (5.85/58.5) / 0.5

              = 0.1 / 0.5

              = 0.2 M

Answer 2

Answer:

The molarity of the
