How do you calculate volume of gas from pressure?

First, let’s review the ideal gas law, PV = nRT. In this equation, ‘P’ is the pressure in atmospheres, ‘V’ is the volume in liters, ‘n’ is the number of particles in moles, ‘T’ is the temperature in Kelvin and ‘R’ is the ideal gas constant (0.0821 liter atmospheres per moles Kelvin).

How many moles of oxygen will occupy a volume of 2.5 liters at 1.2 atm and 25 C?

123 mols 2
1. How many moles of oxygen will occupy a volume of 2.5 liters at 1.2 atm and 25° C? PV = V (1.2 n. 0821) (298) = 123 mols 2.

How many moles of gas are in 890.0 mL?

So, the number of moles of a gas contained in 890.0 mL at 21${}^\circ C$ and 750.0mmHg pressure is 0.036 moles.

How many moles of gas does it take to occupy 120.0 liters at a pressure of 2.3 atmospheres and a temperature of 340 K?

9.89 mols
n = PV (2.3atm/120 L) =9.89 mols P = 2.3 atm RT (0,0821 (afm) ( 340k) T = 340k n=?

What is the volume of 1 mole of gas at a temperature of 273 K and a pressure of 1.0 atm?

22.414 L
If you noticed, we calculated the value of the proportionality constant R based on the fact that exactly one mole of a gas at exactly 1 atm and at 0 ˚C (273 K) has a volume of 22.414 L. This is one of the “magic numbers in chemistry; exactly one mole of any gas under these conditions will occupy a volume of 22.414 L.

What is the temperature at which the sample occupies 292 ml?

The next day, the sample occupies 292 mL at a temperature of 11°C. What is the new pressure of the gas? A balloon is inflated with 2.42 L of helium at a temperature of 27°C. Later, the volume of the balloon has changed to 2.37 L at a temperature of 19°C and a pressure of 99.7 kPa.

What is the volume of SO2 gas at 23 degrees Celsius?

A sample of SO2 gas has a volume of 1.16 L at a temperature of 23°C. At what temperature will the gas have a volume of 1.25 L? A balloon is inflated with 6.22 L of helium at a temperature of 36°C.

What is the pressure when a balloon is inflated with helium?

A balloon is inflated with 2.42 L of helium at a temperature of 27°C. Later, the volume of the balloon has changed to 2.37 L at a temperature of 19°C and a pressure of 99.7 kPa. What was the pressure when the balloon was inflated?

How does the gas law calculator work?

The gas law calculator uses a combination of several formulas for the behavior of gases which can be derived from four separate gas law formulas and result in the ideal gas formula shown below. The ideal gas law is the equation for the state of a hypothetical ideal gas.
