What is the molar mass of gas that, at STP, has a volume of {eq}100\;ml {/eq} and a mass of {eq}0.125\;g {/eq}?Molar Mass of a Gas:We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in ...
Suppose 167 torr of NO2 and 0.780 atm of O2 are placed in a 1.00 L container at 27.0 degrees Celsius. If the volume of the container is reduced to 500.0 mL, what will the new total pressure be? Assume the temperature of the co...
The molar heat capacities for N2 gas at 25 degrees Celsius are Cv = 20.8 JK/Kmol and Cp = 29.1 J/Kmol. What is the change in internal energy when one mole of the N2 gas is heated from 25 to 50 at constant pressure? A sample of gas has a volume of 215 cm^3 at 23.5 degrees ...
To find the relative molecular mass (molar mass) of the gas given that 5.6 liters of it at STP has a mass of 12 grams, we can follow these steps:1. Understand the Relationship at STP: At Standard Temperature and Pressure (ST
STP is one atmosphere of pressure at 0 degrees C. Since this would be a freezing temperature at sea level, dry air is less dense than the cited value most of the time. However, air typically contains a lot of water vapor, which would make it denser than the cited value. ...
The volume of a gas is a function of both pressure and temperature. At STP, 1 mol of gas occupies 22.4 liters (L) of volume. In other words, the molar volume of a gas at STP is 22.4 L. This volume can be found using the ideal gas law: PV=nRT (n = number of moles, R = ...
The Ideal gas equation is represented as PV=nRTwhere, P=pressure, V=volume, n=moles, R=gas constant, T=temperatureAnswer and Explanation: Given: At STP P=1 atm, T=273 K, also V=30 L, molar mass methane =16 g/mol, R=0.0821 L atm/mol K, Apply...
To find the mass of 50 cm³ of carbon monoxide (CO) at standard temperature and pressure (S.T.P.), we can follow these steps:1. Understand the Volume Conversion: - Given volume = 50 cm³. - Since 1 cm³ = 1 mL, ther
as its STP to better reflect ambient conditions of the area. The Society of Petroleum Engineers, for example, defines standard conditions as 59 degrees Fahrenheit (15 degrees Celsius) and 1 bar. When working with engineering designs, it is important for a person to understand the designer's in...
