What mass of SO2 contains the same number of moles as are in 2g of NH3?

PLease do help , and yes, please do tell the real logic behind it!

thank you 🙂

1 mol of NH3 has a weight of about 17 g (N = 14 g, 3 H = 1 g each)

So, 2 g / 17 g per mol = .118 mols approximately.

1 mol of SO2 has a weight of about 64 g

.118 mols x 64 g per mol = 7.53 g of SO2.

The logic is: convert molecular weight to mols, then convert an equivalent amount of moles to the molecular weight of the new compound.

You may need to round this answer, depending on how many significant figures your teacher wants.
