Question

calculate the mass of the solute of 250 cm^3 of NH2SO4​

Answer 1

this is ur answer...I hope this will help u

Answer 2

Answer:

2)

N = 1

N = M * x ( where is x valancy factor)

1 = M * 2 ( as 2 H ions are present in h2so4)

M = 1/2

M =  no. of moles / vol. of the solution

1/2 =  given mass / molecular mass * vol. of solution

1/2 = given mass*1000/ 98 * 250      ( mol. mass of h2so4 = 98)

given mass =  98 / 2*4 = 12.25 g
