The formula for the molecular formula is molar mass/ empirical formula
So, the empirical formula of C3H7 is equal to C*3 + H*7 which is equal to 12*3 + 7. Then use the molecular formula = 86 / (12*3+7) = 2
Therefore, the molecular formula is 2 times the empirical formula which is C6H14.
Wavelength is measured from crest to crest.
Answer:1 atm = 101,325 Pa
So, you convert 33.7 KPa to Pa and divide by 101,325, as follows:
3.7 KPa (1 x 10^3Pa / 1 KPa) (1 atm / 101,325 Pa) = .33 atm
As you can see 33.7 KPa, which is equal to .33 atm, is greater than 0.25.
Explanation: why didnt you just look this up jeez
