Question

4. Uxygen used in nospitais and laboratories is often obtained irom cyinders containing liquetiea oxygen. ii a cyiinder contains 2SUXIU Kg of liquid oxygen, now many lsters of oxygen can be produced at 1.40atm of pressure at room temperature 24.0?? 5. Betore most surgicai operations, patients are generaly injected witn cyciopropane Cn,cnioroetnane Ch,Ch-ci or cnioromeinane Ch,-Ci wnicn are usea as an anaesthetic. It a sample 01 cyclopropane is stored in a g.DUL container at iu-satm and 25 C is transterrea to a 6.5UL container at a temperature of 82.0r, what is the resuiting pressure

Explanation / Answer

I am solving the Q4 (first question) as per Chegg guidelines, post multiple question to get the remaining answers

Q4)

Mass of liquid oxygen = 2.50 * 10^3 Kg = 2.5 * 10^6 grams

Number of moles of oxygen = Mass/molar mass = 2.5 * 10^6/32 = 78125 moles

Using ideal gas equation

PV = nRT

1.40 * V = 78125 * 0.0821 * (273.15+24.6)

V = 1.36 * 10^6 L
