# Frequent question: What is the volume of 3 5 moles of hydrogen gas at STP?

Contents

The volume is 68.1 L at STP .

## How do you calculate volume of hydrogen at STP?

1. PH2 = 749.2 – 19.89 = 729.31 mm of Hg = P1.
2. Volume of H2(g) = 38.2 mL = 0.0382 L = V1.
3. At STP:
4. Pressure = 760 mm of Hg = P2.
5. Temperature = 273 K = T2.

## What is the volume of hydrogen gas at STP?

Today you are going to prove experimentally that the volume of one mole of a gas at standard temperature & pressure (STP) occupies a volume of 22.4 liters or 22,400 milliliters. The numerical values that are used for STP are one atmosphere (1 atm) and zero degrees Celsius (0°C) or 273 Kelvin (273K).

## What volume will 5.00 mol of H2 gas 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 .

## How do you convert moles to volume at STP?

Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of 1 mole = 22.4 L is the basis for the conversion factor.

## How do you calculate hydrogen volume?

1. Step 1 – Calculate the amount of sodium. Amount in mol = Amount in mol = …
2. 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
3. Step 3 – Calculate the volume of hydrogen. Volume = amount in mol × molar volume. Volume = 0.10 × 24.

## What is STP formula?

STP in chemistry is the abbreviation for Standard Temperature and Pressure. STP most commonly is used when performing calculations on gases, such as gas density and is represented as STP = V*(273/T)*(P/100) or stp = Volume of Gas*(273/Temperature of Gas)*(Pressure of Gas/100).

## 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 volume of 5.0 g of AR at STP?

The volume of 5.0 g CO2 is 2.6 L CO2 at STP.

## What is the volume of 1 mole of a gas at STP?

What is the volume of 1 mole of an ideal gas at STP (Standard Temperature and Pressure = 0 °C, 1 atm)? So, the volume of an ideal gas is 22.41 L/mol at STP. This, 22.4 L, is probably the most remembered and least useful number in chemistry.

## What is the volume of 2 moles of oxygen gas at STP?

Answer. 1mol O2 occupies 22.4L of volume at STP. so 2mol O2 occupies 44.8L of volume at STP.

## What is the formula for pressure and temperature?

The equations describing these laws are special cases of the ideal gas law, PV = nRT, where P is the pressure of the gas, V is its volume, n is the number of moles of the gas, T is its kelvin temperature, and R is the ideal (universal) gas constant.

## What is the formula for moles?

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).
