At STP, one mole of any gas occupies 22.4 litres of volume. One mole of a gas is given by the Avogadro’s number i.e. NA and it is given as 6.023×1023. According to this, one mole of hydrogen gas at STP will occupy 22.4 L of volume. Therefore, 2 moles of hydrogen gas will occupy a volume twice of 22.4 L i.e. 44.8 L.
What is the volume of 2.00 mole of hydrogen gas H2 at STP?
At STP, 2 moles of hydrogen can occupy a volume of 2×22. 4=44. 8 liters.
What volume is taken by 2 moles of hydrogen?
from equation: 2 moles HCl ==> 1 mole H2 (mole ratio 2:1) so 0.25 mol HCl ==> 0.125 mol H2, volume 1 mole gas = 24 dm. so volume H2 = 0.125 x 24 = 3 dm.
What is the volume of 2 grams of H2 gas at STP?
Answer. Hence volume at STP=22.4litres which is the molar volume.
What volume of H2 gas is produced at STP?
242 times the 22.4 will give us 5.42-liters of hydrogen gas at S.T.P.
How do I find the volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
What is the volume of oxygen?
We now know that the volume of 2.155 × 10-3 moles of oxygen is about 52.88 cm3. Use this information to calculate the volume of one mole of oxygen. (Your answer may not be exactly this figure, but should be close to it.) At STP, all gases have the same molar volume, which is about 24,000 cm3.
What is the formula for volume of gas?
It can be written as: V = nRT/P. “P” is pressure, “V” is volume, n is the number of moles of a gas, “R” is the molar gas constant and “T” is temperature.
How do you calculate volume in RTP?
Calculate the volume of 0.5 mol of carbon dioxide at rtp.
- volume = 0.5 × 24 = 12 dm 3
- Remember that 1 dm 3 = 1 000 cm 3 so the volume is also 12 000 cm 3
- The equation can be rearranged to find the number of moles, if the volume of gas at rtp is known:
- number of moles = volume of gas at rtp ÷ 24.
How do you calculate hydrogen volume?
- Step 1 – Calculate the amount of sodium. Amount in mol = Amount in mol = …
- Step 2 – Find the amount of hydrogen. From the balanced equation , the mole ratio Na:H 2 is 2:1. Therefore 0.20 mol of Na produces = 0.10 mol of H 2
- Step 3 – Calculate the volume of hydrogen. Volume = amount in mol × molar volume. Volume = 0.10 × 24.
What is the volume of 1 gram of H2 at STP?
So Volume of 1 gram equivalent of H2 gas at NTP =22.4/2=11.2 Litres.
What is the volume of 1 gram hydrogen gas at STP?
So Volume of 1 gms of H2 gas at NTP =22.4/2=11.2 Litres.
How many liters are in 100g of hydrogen at STP?
The answer is 21.5 L .
What is the volume of hydrogen gas?
Molar volume, or volume of one mole of gas , depends on pressure and temperature, and is 22.4 liters – at 0 °C (273.15 K) and 1 atm (101325 Pa), or STP (Standard Temperature and Pressure), for every gas which behaves similarly to an ideal gas.
What is the total volume of hydrogen gas and oxygen gas?
The volumes required (uncompressed) can be derived from the approximation of 22.4L/mol for ideal gases. The volume of hydrogen required is 205.4 moles * 22.4L/mol = 4601L. The volume of oxygen required is 102.7 moles * 22.4L/mol = 2300L.
