Homework Help Overview

The problem involves calculating the volume occupied by a specific mass of molecular oxygen gas under given pressure and temperature conditions. The subject area pertains to gas laws, specifically the ideal gas law.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to apply the ideal gas law (PV = nRT) to find the volume but encounters a discrepancy in their calculations. Participants question the mass used in the calculation, noting a potential error in converting kilograms to grams.

Discussion Status

The discussion is ongoing, with participants pointing out inconsistencies in the original poster's calculations. There is a focus on clarifying the correct mass of oxygen to be used, and the conversation is exploring the implications of this error.

Contextual Notes

Participants are addressing a possible typo in the mass value used in the calculations, which may affect the outcome. The original poster's reference to a different mass (532g) raises questions about the accuracy of their inputs.

Homework Statement


A mass of 0.582 kg of molecular oxygen is contained in a cylinder at a pressure of 1.0 × 10^5 Pa and a temperature of 1°C. What volume does the gas occupy?


Homework Equations



PV = nRT

The Attempt at a Solution



15.9994 * 2 = 31.9988 amu
532g / 31.9988 amu = 16.62604 mol

K=1 + 273 = 274

(16.62604 x 8.3145 x 274)/100,000
= .3788m^3

This is wrong according to my book...Any ideas why?
 
Physics news on Phys.org
The problem statement lists 0.582kg, and you use 532g in your calculation.
 
According to google.com: 0.582 kilograms = 582 grams?
 
Yeah, so why'd you use 532 in your calculation? A typo?
