Gas cylinders, each containing 30 kg of a mixture of 75 mol% acetylene (c2h2) and balance n2 are available. how many cylinders are needed to produce 1.5 m3 of the gas mixture at 200 atm (abs) and 150°c?

- 8 cylinders are needed to produce the required amount of the gas.

Solution: First we calculate the moles of the gas for it's volume at 200 atm and 150 degree C using ideal gas law equation:

PV = nRT

V = = 1500 L

P = 200 atm

T = 150 + 273 = 423 K

R =

Let's plug in the values in the equation:

n = 8638.5 mol

Acetylene and nitrogen are 75 mol% and 25 mol% respectively in the cylinder.

So, moles of acetylene = = 6478.9 moles

moles of nitrogen = 8638.5 - 6478.9 = 2159.6 moles

mass of acetylene = 6478.9*26 = 168451.4 g

mass of nitrogen = 2159.6*28 = 60468.8 g

Total mass of mixture = 168451.4 g + 60468.8 g = 228920.2 g = 228.92 kg

number of cylinders = = 7.63 = 8

So, 8 cylinders are needed.

for points guys

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
