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
the person that is correct is the manufacturer because you cannot make a knife out of Rosewood. Also Rosewood trees are extremely few and far between plus it is illegal to harvest rosewood trees for their lumber since that type of tree genus is also slowly becoming extinct
hope this helps:)
