 # How Do You Calculate Hydrogen Volume?

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

According to Avogadro’s law, the volume of one mole of any gas at Standard Temperature and Pressure (STP = 273 K and 1 atm) is 22.4 L.

Two important Gas Laws are required in order to convert the experimentally determined volume of hydrogen gas to that at STP..

## What is the volume of 1 gram of hydrogen gas?

22.4 LAccording to the universal gas constant, 1 mole of ANY gas at STP occupies 22.4 L of space, and since the molar mass of Hydrogen is 1 g, we can say that 1 g of Hydrogen=one mole of Hydrogen, so 1 g of Hydrogen occupies 22.4 L of space.

## What is the volume of 2 gram of hydrogen?

it occupies 22.4 litres.

## How many kWh is 1kg of hydrogen?

33.33 kWhHydrogen is an excellent energy carrier with respect to weight. 1 kg of hydrogen contains 33.33 kWh of usable energy, whereas petrol and diesel only hold about 12 kWh/kg (see www.h2data.de). In terms of volumetric energy density however, hydrogen is outperformed by liquid fuels.

## What is specific volume of steam?

SPECIFIC VOLUME OF STEAM  The specific volume is the volume occupied by the unit mass of a substance . It is expressed in m³/kg . The volume of water and steam increase with the increase in temperature. … Vsup = Specific volume of superheated steam at pressure P.

## Why is hydrogen measured in kg?

kilogram (\$/kg)? Because the hydrogen is delivered in a compressed gaseous form, volume measurement would not be suitable due to the dependency on pressure and temperature of the gas. … Consequently, the kilogram was adopted as the quantity unit for commercial sales of hydrogen vehicle fuel.

## How do you calculate standard volume?

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. Record the molar gas constant “R”. R = 8.314472 J/mole x K.

## What is the volume of 3.5 g of hydrogen?

2 g occupies 24 dm3, so scaling up for the volume of hydrogen … 3.5 g will have a volume of 3.5/2 x 24 = 42 dm3 (or 42000 cm3)

## How do you find molar volume at STP?

At standard Temperature and Pressure (STP) the molar volume (Vm) is the volume occupied by one mole of a chemical element or a chemical compound. It can be calculated by dividing the molar mass (M) by mass density (ρ). Molar gas volume is one mole of any gas at a specific temperature and pressure has a fixed volume.

## What does 1 cubic meter of hydrogen weigh?

0.082 kilogramHydrogen weighs 8.2 × 10-5 gram per cubic centimeter or 0.082 kilogram per cubic meter, i.e. density of hydrogen is equal to 0.082 kg/m³; at 0°C (32°F or 273.15K) at standard atmospheric pressure.

## How much does oxygen gas weigh?

In reality, oxygen gas has a density of 1.429 grams/liter at the so-called standard pressure and temperature (basically room temperature and atmospheric pressure) while carbon dioxide has a density of 1.977 grams/liter.

## What is standard volume?

The volume of an ideal gas at standard temperature and pressure: 22.414 liters.

## What is the volume at NTP?

NTP – Normal Temperature and Pressure At these conditions, the volume of 1 mol of a gas is 24.0548 liters.

## How many liters are in 1 kg of hydrogen?

## What is the volume of 1 kg of hydrogen?

A volume of around 11 m3 (which is the volume of the trunk of a large utility or commercial vehicle) is needed to store just 1 kg of hydrogen, which is the quantity needed to drive 100 km.

## 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.
