At what temperature will a 56 gram sample of nitrogen gas have a volume of 1250 cm^3 at 95.3 kPa? (Answer is 7.17 K. I just need the work)

i believe it is 40–40–20%

explanation:

"you start with 15.67 g mgco3-xh2o, when heated and all the water is removed, you are left with 7.58 g mgco3 only.

therefore, you had 15.67 - 7.58 = 8.09g h2o  

moles of each :

7.58g mgco3 = ? moles = 7.58g / 83.4g/mole = 0.09moles  

8 09g h2o = ? moles = 8.09g / 18g/mole = 0.44moles  

molar ratio between the two by dividing both numbers by the smallest number :

0.09 / 0.09 = 1  

0.44 / 0.09 = 4.8  

mgco3-5h2o"

1.solid

2.carbon dioxide

3.helium

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
