Question

2HN3 + H2SO4 ===> (NH4)2SO4

What mass of H2SO4 is needed to form 1.00 tonne (1000kg) of (NH4)2SO4?

Answer 1

(NH4)2SO4 = 7575.8 moles

H2SO4 = 7575.8 moles

Answer 2

@chmvijay

Answer 3

oh! (NH4)2SO4 = 132 , H2SO4 = 98

Answer 4

u didnt convert kg to g

Answer 5

arent u suppose to use the mass of (NH4)2SO4 and it is molecular weight, not using the mass of (NH4)2SO4 with the molecular mass of H2SO4

Answer 6

and the mass of (NH4)2 SO4 is given = 1000,000g

Answer 7

my q' is y are u using the mass of (NH4)2SO4 with the molecular weight of H2SO4

Answer 8

is this how this can be done

Answer 9

you have the molar masses of H2SO4 and (NH4)2SO4

Answer 10

yeah its stated above

Answer 11

98 for H2SO4 and 132 for (NH4)2SO4

this means,
98 grams of H2SO4 is needed to form 132 gram of (NH4)2SO4
ok with this?

Answer 12

ahan

Answer 13

so my working out is not correct?

Answer 14

you can do this question by firstly calculating the number of moles and then converting into mass

but i think this is straightforward way to solve the question/.

the above method is also correct,
you can proceed that way too

Answer 15

oh k thanks

Answer 16

wlcome

now you can do the ques. i guess easily
