Question

a Find the
molarity of a solution of
H₂SO4 having 4.9g of it
of it dissolved
in soocny of
5ool of solution.
ang :-​

Answer 1

Answer:

Molarity = 10^-4 Molar

Explanation:

number of moles of h2so4 = given weight /molar weight

given weight = 4.9g

molar weight = 2 + 32 + 64 = 98g

element   weight

 H              2 x 1g

 S               1 x 32g

 O               4 x 16g

number of moles = 4.9 / 98 = 1/20moles

molarity = number of moles/volume in litre

volume = 500L

molarity = (1/20)÷500

molarity = 10^-4M
