Answer:
it should be 310.18 g/mol :)
Answer:
Explanation:
%Carbon = mass of carbon / mas of C13H18O2) X100%
= 13X12/ (13X12+18+2X16)X100%
= 156/206) X100%= 75.7%
Answer:
Kelvin
Explanation:
As we know that
![PV = nRT\\](https://tex.z-dn.net/?f=PV%20%3D%20nRT%5C%5C)
Where P is the pressure in atmospheric pressure
T is the temperature in Kelvin
R is the gas constant
V is the volume in liters
![R = 0.08206](https://tex.z-dn.net/?f=R%20%3D%200.08206)
Substituting the given values in above equation, we get -
![1.35 * \frac{50}{1000}= 4.5 * 0.08206* T\\](https://tex.z-dn.net/?f=1.35%20%2A%20%5Cfrac%7B50%7D%7B1000%7D%3D%204.5%20%2A%200.08206%2A%20T%5C%5C)
On rearranging, we get
![T = \frac{1.35*50}{1000*0.08206*4.5} \\](https://tex.z-dn.net/?f=T%20%3D%20%5Cfrac%7B1.35%2A50%7D%7B1000%2A0.08206%2A4.5%7D%20%5C%5C)
