Question

What is the volume of a 0.5 mol/L solution of sodium nitrate given 12.75 g?

Answer 1

Answer:

Explanation:

Volume of 0.5 mol/l solution of NaNO3

weight given is 12.75 g

Molecular mass of NaNO3 = 23+14+48 = 85

Moles of NaNO3 = given mass / molecular mass

                             = 12.75/85 = 0.15 moles

Molarity is given !

So molarity = moles / volume

0.5 = 0.15 / vol

so Volume is 0.3 Litres

please mark as brainliest !

HAVE A GOOD DAY

Answer 2

Answer:

Explanation:

moles of NaNO₃= mass/molar mass

                          = 12.75/85

                          = 0.15 moles

molarity = moles of solute / volume of solution

0.5= 0.15/volume

volume= 0.15/0.5

           = 0.3 litres
