Answer:
270.34
Explanation:
pressure, 550 pressure, 270.34
______________ = ___________
177 degree celsius. 87 degree celsius.
550 x 87 / 177 = 270.34
Answer:
3.8 x 10²⁴molecules
Explanation:
Given parameters:
Number of moles = 6.32moles
Unknown:
Number of molecules = ?
Solution:
The number of moles can be used to derive the number of molecules found within a substance.
Now,
1 mole of substance contains 6.02 x 10²³ molecules
6.32 mole of PBr₃ will contain 6.32 x 6.02 x 10²³ = 3.8 x 10²⁴molecules
P1 = 5.7atm V1 = 26L
P2 = ? V2 = 6.5 L
By Boyles Law,
P1V1 = P2V2
5.7 × 26 = P2 × 6.5
By solving,
P2 = 22.8atm.
Answer:
it would be colder on the mountains becouse there is less air up there and it would be a lot more humid down by the ocean
Explanation:
2 mol KClO₃ - 3 mol O₂
x mol KClO₃ - 9 mol O₂
x=9*2/3= 6 mol
