A canister of acetylene has a volume of 42 L. The temperature of the acetylene is 305 K and the pressure is 780 torr. Determine
stellarik [79]
First, we need to assume acetylene to adapt an ideal gas behavior. So, we can use the Ideal Gas Law:

PV = nRT

Given:

V = 42 L
T = 305 K
P = 780 torr = 1.026 atm 
R = gas constant, 0.0821 L atm/ mol K
n = amount of gas in the canister

1.026 atm * 42 L = n * 0.0821 L atm/mol K * 305 K

n = 1.72 moles of gas

Molar mass of carbon
Taya2010 [7]

Answer: 12.011g/mol

Explanation: The molar mass of any element is usually stated at the bottom of periodic table (depending of your table anyways). Remember that the periodic table speaks to you in moles so every molar mass under the element is for 1 mole. By this I mean for example, 1 mole of Carbon = 12.011g of Carbon.
