What is the volume of He at STP?
The atomic weight of helium is 4 g/mol, so 6 g is 1.5 moles. The volume occupied at STP, therefore, is 22.4 x 1.5 = 33.6 litres.
How do you calculate L in STP?
Substituting these conversion in the ideal gas law produces a value of RT/P that is 0.022414 cubic meters/mole at STP. Thus, at STP, the ideal gas law can be written V = 0.022414n. Divide the mass of the gas weight by its molar mass to calculate n — the number of moles.
How many liters are in a gram of STP?
Standard pressure is 1 atmosphere or 760 mm Hg (also called “torr”). 1 mole of any gas at STP occupies 22.4 liters of volume. Using this information, the volume occupied by any number of moles (or grams) can be determined.
What volume will 5.0 g of h2 occupy at STP?
So, you know that under STP conditions for pressure and temperature, 1 mole of any ideal gas will occupy 22.4 L .
What is mass at STP?
The formula D= M/V is used at STP with M being equal to the molar mass and V being molar volume of a gas (22.4 liter/mole).
What is the volume of 1 gram of gas at STP?
At STP, the volume of 1 g of a gaseous substance is 280 mL.
How to calculate molar volume of a gas at STP?
Using the Ideal Gas Law, you would find the volume of 1 mole of a gas at Standard Temperature and Pressure (STP). STP = 1 atm of pressure and 273 K for temperature P = 1 atm
How to convert moles to liters at STP?
To convert between moles and the volume of a gas at STP, we will use the factor label method discussed in the first unit. This conversions relies on the fact that a mole of gas at STP has a volume of 22.4 L. It is important to note, however, that if the conditions of the gas are different this conversion will NOT work.
Can you convert grams of gas to liters of gas?
Because the molar volume is the same for all ideal gases and is known, we can convert from grams to liters and vice versa if we know the gas formula. These are steps to convert from grams of gas to liters of a gas: find the volume by multiplying the number of moles to molar volume.
What is the volume of 15.0 g F2?
The volume of 15.0 g F2 at STP is 8.97 L. First determine the molar mass of fluorine gas (F2), then determine the moles of fluorine gas. The molar mass of fluorine is its atomic mass from the periodic table in g/mol. Multiply the molar mass of F times the subscript 2 in the formula for fluorine gas, F2. Divide the given mass by the molar mass.
