Answer:
58.5g/mol
Explanation:
Given parameters:
Mass of gas = 4.25g
Volume = 1.7L
Pressure = 883mmHg
760mmHg = 1 atm
883mmHg = 
= 1.16atm
Temperature = 58°C = 58 + 273 = 331K
Unknown:
Molar mass of sample = ?
Solution:
To solve this problem, we use the ideal gas equation to find the number of moles;
PV = nRT
P is the pressure
V is the volume
n is the number of moles
R is the gas constant = 0.082atmdm³mol⁻¹K⁻¹
T is the temperature
n = 
= 
= 0.07mole
Since;
mass = number of moles x molar mass
4.25 = 0.07 x molar mass
Molar mass = 58.5g/mol
The answer is b, the only way to prove a theory true. Hope this helps :)
The answer is number four but the same time I don’t really know it’s like ha ha ha ha ha ha ha ha ha ha sorry
Answer: Weather refers to short term atmospheric conditions while climate is the weather of a specific region averaged over a long period of time. Climate change refers to long-term changes.
Answer:
2-methylene propylbenzene
Explanation:
The Wittig Reaction is a reaction that converts aldehydes and ketones into alkenes through reaction with a phosphorus ylide.
The ketone in this case is 1-phenylpropan-1-one. The provided phosphonium ylide is shown in the image attached. The reaction involves;
i) alkylation
ii) addition
The product of the major organic product of the reaction is 2-methylene propylbenzene.
