Best answer: What is the number of moles in 500l of the gas at STP?

How do you find the number of moles of gas at STP?

To go from grams to moles, divide the grams by the molar mass. 600 g58.443 g/mol = 10.27 mol of NaCl. It has been found that 1 mol of any gas at STP (Standard Temperature and Pressure = 0 °C and 1 atm) occupies 22.4 L. 6.00 mol×22.4 L1 mol = 134.4 L of CO.

What is the number of moles at STP?

The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.

What is the number of moles in 9.63 L of He gas at STP?

9.63L/22.4L. mole = 0.430 mole.

How many moles are in 20l of gas?

An ideal gas at STP occupies 22.4 liters. Calculating Oxygen as if it were an ideal gas there are . 893 moles of Oxygen in 20.0 liters.

What is the mole formula?

Avogadro’s number is a very important relationship to remember: 1 mole = 6.022×1023 6.022 × 10 23 atoms, molecules, protons, etc. To convert from moles to atoms, multiply the molar amount by Avogadro’s number. To convert from atoms to moles, divide the atom amount by Avogadro’s number (or multiply by its reciprocal).

How many moles of electrons weigh 1kg?

Or, 1 kg will contain = $dfrac{1}{{9.108 times 6.022}} times {10^8}$ moles of electrons. Thus, $dfrac{1}{{9.108 times 6.022}} times {10^8}$ moles of electrons will weigh one kilogram. So, the correct answer is “Option D”.

How many liters is 7 moles of air at STP?

At STP, gases have a volume of 22.4 L per mole.

What is one mole of a gas?

The molar volume of a gas is the volume of one mole of a gas at STP. At STP, one mole (6.02 × 10 23 representative particles) of any gas occupies a volume of 22.4 L ( Figure below ). A mole of any gas occupies 22.4 L at standard temperature and pressure (0°C and 1 atm).
