Calculate Volume of Ammonia for 1 Tonne Ammonium Nitrate

[newkidintownu]

Please can someone help me with the following question:

Calculate the volume of ammonia required, in cubic metres at stp, to produce one tonne of ammonium nitrate.

I know how to work out the mass of ammonia in one tonne of ammonium nitrate but am struggling with volumes...help needed!

At STP, one mole of an ideal gas occupies 22.4 Litres. 1 Litre=1000 cm^3. Can you carry on from there?

I'm still a bit unsure...can you help further please

Let m be the mass in grammes of NH3 in one tonne of ammonium nitrate..
Let M be the molecular weight of NH3.
The number of moles of NH3 is m/M and the volume of NH3 is
22.4 (Litre/mole) . (m/M) mole = 22 400 cm³ (m/M)
=22400(m/M) (cm (1 metre/(100 cm))³
=0.0224 (m/M) metre³

Please check my arithmetic!

Thanks...I was having trouble with converting volume to mass but now that you have explained this it is now clear. Your help with this is much appreciated...thanks again
