I had a question on a test which asked me the volume of sulphur dioxide that would be formed if 12.7g of copper were used. How do you calculate gas volume when you only have the mass?
Julian_delia said:So if the STP of any gas is 22.4L per mole
all you have to do is to multiply 22.4L with the number of moles of the specified gas?
The gas volume at STP (Standard Temperature and Pressure) can be calculated by using the ideal gas law equation: V = nRT/P, where V is the volume of the gas in liters, n is the number of moles of gas, R is the universal gas constant (0.0821 L atm/mol K), T is the temperature in Kelvin (273 K at STP), and P is the pressure in atmospheres (1 atm at STP).
STP stands for Standard Temperature and Pressure, and it is the standard set of values used to calculate gas volume. STP is defined as a temperature of 273 Kelvin (0 degrees Celsius) and a pressure of 1 atmosphere (760 mmHg or 101.3 kPa).
The ideal gas law is a mathematical equation that describes the relationship between the pressure, volume, temperature, and number of moles of a gas. It is written as PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T is the temperature in Kelvin.
Yes, gas volume can be calculated at different temperatures and pressures using the ideal gas law equation. However, the temperature and pressure values must be converted to Kelvin and atmospheres respectively before plugging them into the equation.
The units for gas volume at STP are liters (L) or cubic centimeters (cm3). These units can be converted to other units of volume, such as milliliters (mL) or cubic meters (m3), if needed.
