Question

If M\20 H2SO4 solution has 2.5 g/cc density, then
molality of solution is
(1) 0.03 m
(2) 0.01 m
(3) 0.02 m
(4) 0.05 m​

Answer 1

Answer:

0.03 is the answer of this

Answer 2

Answer: Molality=Molarity×1000÷1000×density-(Molarity×molecular weight of solute

Molarity=1/20,,, density=2.5,,, molecular weight of solute=98

Explanation:molality=1/20×1000÷1000×2.5-1/20×98

=50÷2500-4.9

=50÷2491.1=500÷24911==0.0200

So option 3 is correct

I hope you understand well thank you
