Question

Battery acid is 4.22M of H2SO4 has density
121 g/cm3
Calculate molality​

Answer 1

Answer:

5.298mol(kg) is the answer I hope it will help you please thanks

Answer 2

Answer:

35 MOLAL OR 35 m.

Explanation:

MOLARITY OF BATTERY ACID= 4.22 MOLAR.

SO YOU HAVE 4.22 MOLES OF H2SO4 IN 1LITRE OF SOLUTION.

NO. OF MOLES OF SOLUTE= 4.22 MOLE

NOW DENSITY= 121 g/cm3

MASS OF SOLVENT= DENSITY X VOLUME= 121 X 1 = 121 GRAM SOLVENT= 121/1000 KG SOLVENT.

SO MOLALITY= MOLES OF SOLUTE/ MASS OF SOLVENT IN KG= 4.22/121/1000= 34. 87 MOLAL= 35 MOLAL APPROX.
