Hydrazine N2 H4 a base like ammonia can react with sulfuric

Hydrazine, N2 H4, a base like ammonia, can react with sulfuric acid 2 N2H4(aq) + H2 so,(aq) 2 N2Hs+ (aq) + SO42-(aq) What mass ofhydrazine reacts with 200 mL of152 M H, SO? Mass = Submit Answer Try Another Version 3 itern attempts remaining

Solution

For the given reaction , we have

volume of H2SO4 = 200 ml = 0.200 L

Molarity = 0.152 M

therefore

moles of H2SO4 used = molarity x volume = 0.152 mol/L x 0.200 L = 0.0304 moles

and

moles of Hydrazine used = 2 x moles of H2SO4 = 2 x 0.0304 mole = 0.0608 mole

and

mass of hydrazine used = moles x molar mass = 0.0608 mole x 32.0452 g/mol = 1.948 g
