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.
