Question

The Haber process can be used to produce ammonia (NH3) from hydrogen gas (H2) and nitrogen gas (N2). The balanced equation for this process is shown below.

3H2 + N2= 2NH3

The molar mass of NH3 is 17.03 g/mol. The molar mass of H2 is 2.0158 g/mol. In a particular reaction, 0.575 g of NH3 forms. What is the mass, in grams, of H2 that must have reacted, to the correct number of significant figures?
0.1
0.102
0.10209
0.1021 v

Answer 1

@Somy

Answer 2

would it be 0.1021?

Answer 3

did u guess again...

Answer 4

yeah but looks like it would be 0.1021 or 1.02

Answer 5

am i right?

Answer 6

do same kind of calculation as in previous question

Answer 7

that would get me 0.102

Answer 8

~_~ nope
take molecular mass of NH3 and mass of NH3

Answer 9

0.10209

Answer 10

ok this is the answer
i don't see you solving anything anyways.
