Answer:
d. The number of moles
Explanation;
- According to the ideal gas;
P = nRT
where, P is the pressure, n is the number of moles, R is the ideal gas constant and T is the absolute temperature.
- Charles's law and Boyle's law revolve around, volume, temperature and pressure.
- According to Charles's law volume and temperature of a fixed mass of a gas are directly proportional at constant pressure.
- That is; V α T
- While based on Boyle's law, volume and pressure of a fixed mass of a gas are inversely proportional at constant temperature.
- That is, Pα 1/V
- We can, thus see that ideal gas law allows you to calculate number of moles unlike the case with Charles's and Boyle's law.
the second one is space while the first one is shape
Answer:C2H6N
Explanation:
Putrescine formula is C4H12N2
Assuming 100g sample is present
The percent changes to grams and it is converted to moles by dividing it with the atomic masses.
C= 54.50g/12 = 4.541moles
H = 13.73g/1 = 13.73moles
N= 31.77g/14 = 2.269moles
Divide through with the smallest moles value.
C= 4.541/2.269 = 2
H= 13.73/2.269=6
N= 2.269/2.269=1
Therefore the empirical formula is
C2H6N
