There is no hydrogen in ammonium sulfide it is just 1 ammonium and 1 sulfer
Answer:
mass of ice is 1.75
Explanation:
Using, the formula given in the question,
m = Q/HΔf.................. Equation 1
Where Q = Heat, m = mass of ice, HΔf = Latent heat of fussion of for ice.
From the question,
Given: Q = 584.5 J, HΔf = 334 J/g
Substitute these values into equation 2
m = 584.5/334
m = 1.75 kg.
Hence the mass of ice without unit is 1.75
