Need help with these confusing chemistry Questions Help Help Help !
Ive balanced the equation to this which is 2NaN3→ 2Na + 3N2
A) How many grams of NaN3 are required to form 15.0g of N*2 gas?
How on earth do I work this out can someone show me the answer and working out as simply as possible
B) What volume would 15g of N2 gas produce at 170C and standard pressure?
Again confuses the hell outta me

A) work out the moles of using the molarmass of N and 15g. Then just stochiometry to deduce the moles of and from there just work out the grams needed using its molarmass.
For A: work out the mole ratio (3:2)
wWork out the GFM of 2 moles of NaN3 and 3 moles of N2
GFM of 3N2 : GFM 2NaN3
1g 3N2 : GFM 2NaN3 divided by GFM of 3N2
15g : answer from above step.
Hope this helped and made sense!

A) Divide 15g by N2 molar mass to get moles of N2. As the ratio of N2 to NAN3 is 3:2, multiply the moles you just calculated by 2/3 to get the moles of NaN3. Now multiply these moles by NaN3 molar mass to get the grams of NaN3

Ok so mole mass of N2 is 28 I do the division sum 15÷28 = 0.5357
So what do I do with this number multiply it by 2 then divide it by 3 ???? Then multiply it again by 65
And that will be the answer to how many grams I need ?????
