Answer:
4.20 moles NF₃
Explanation:
To convert between moles of N₂ and NF₃, you need to use the mole-to-mole ratio from the balanced equation. This ratio consists of the coefficients of both molecules from the balanced equation. The molecule you are converting from (N₂) should be in the denominator of the ratio because this allows for the cancellation of units. The final answer should have 3 sig figs because the given value (2.10 moles) has 3 sig figs.
1 N₂ + 3 F₂ ---> 2 NF₃
2.10 moles N₂ 2 moles NF₃
--------------------- x --------------------- = 4.20 moles NF₃
1 mole N₂
Their are natural since they come from trees which is natural
Molar concentration is the amount of solute in moles divided by 1 liter of solvent. Then to answer this question, you need to convert the 23g of ammonium chloride into mole unit. Since the mass of nitrogen = 14, helium =1, and chlor= 35.453 then the molecular mass of (NH4)Cl should be: 14+4+35.453= 53.5
Then, the molarity should be: 23g/ (53.5gr/mole)/ (500ml/1000ml)= 0.86molality
Explanation:
I think it's from over population and global warming and we can't completely drink sea water
I hope it helps
Check table T and use the concentration equation. Molarity= moles of solute/ liters of solution.
So 0.240 = x/ 1.65 once u find the # of miles of solute (x=.396) and substitute that
Wait I'm not sure if it's correct
