Well, it depends on what measurements you are using for the MW of H. Say you refer to a mole as 6.022x1023 and H is 1.008. This means that one mole of H weighs 1.008 g. So you use this conversion. Probally a homework problem so i think you can use a calculator. 5.00g H X 1 mol H ---- 1 X 1.008g H
Anyone feel free to correct me!
To determine the number of moles of hydrogen gas present, you need to know the volume and pressure of the gas, as well as the temperature. You can then use the ideal gas law (PV = nRT) to calculate the number of moles of hydrogen gas.
5.0 grams hydrogen gas (1 mole H2/2.016 grams)
= 2.5 moles hydrogen gas
----------------------------------
You get one mole per gram of gas...so it depends on how much you have.

How many moles of hydrigen are present in a 2 grams sample of hydrogen gas?
There are approximately 2 moles of hydrogen gas in a 2 grams sample. This is calculated by dividing the mass of the sample by the molar mass of hydrogen gas, which is approximately 1 g/mol. Thus, 2 grams ÷ 1 g/mol = 2 moles.
How many moles of H2 gas are present in 6.0 L flask at stp?
The answer is 0,2675 moles.
How many moles are in 750 L of hydrogen gas?
750 L hydrogen gas at 0 0C and 1 at is equal to 33,44 moles.
How many moles of gas are present when the volume of gas is 100.0 liters the pressure is 3 atmospheres and temperature is -10C?
The answer is 13,89 moles.
How many moles of of hydrogen gas occupy 112L at stp?
Ideal gas equation. PV = nRT ===============
How many moles of hydrogen gas are in 5.04 grams in hydrogen gas?
To find the number of moles of hydrogen gas, we first need to convert the mass of hydrogen gas from grams to moles using the molar mass of hydrogen gas (2 g/mol). 5.04 grams of hydrogen gas is equal to 5.04 g / 2 g/mol = 2.52 moles of hydrogen gas.
How many moles of hydrigen are present in a 2 grams sample of hydrogen gas?
There are approximately 2 moles of hydrogen gas in a 2 grams sample. This is calculated by dividing the mass of the sample by the molar mass of hydrogen gas, which is approximately 1 g/mol. Thus, 2 grams ÷ 1 g/mol = 2 moles.
How would you find the answer to this question How many moles of HCl can be formed when moles of hydrogen gas react with chlorine?
You can determine the moles of HCl formed by using a balanced chemical equation for the reaction between hydrogen gas and chlorine. Calculate the stoichiometric ratio of hydrogen to HCl in the balanced equation to determine the moles of HCl formed from the given moles of hydrogen gas.
How many moles of H2 gas are present in 6.0 L flask at stp?
The answer is 0,2675 moles.
How many moles of hydrogen gas is required to completely react with chlorine in the following reaction that has a pressure of 735 torr at 34 C in a 450 ml container according to the reaction. H2 Cl2 2?
To find the number of moles of hydrogen gas, we first need to calculate the number of moles of chlorine gas using the ideal gas law formula (PV = nRT). Once we have the moles of chlorine gas, we can determine the moles of hydrogen gas needed for the reaction. In this case, the stoichiometry of the reaction states that 1 mole of chlorine gas reacts with 1 mole of hydrogen gas, so the required moles of hydrogen gas will be equal to the moles of chlorine gas.
How many moles in a gallon of hydrogen?
There are approximately 4.48 moles of hydrogen gas in a gallon at standard temperature and pressure (STP).
How many moles are in 750 L of hydrogen gas?
750 L hydrogen gas at 0 0C and 1 at is equal to 33,44 moles.
How many moles of gas are present when the volume of gas is 100.0 liters the pressure is 3 atmospheres and temperature is -10C?
The answer is 13,89 moles.
How many moles of helium gas (he) are present in 7.2 liters of helium gas at standard conditions?
The number of moles of helium is 0,32.
How many moles are in 18.0grams of hydrogen gas?
To find the number of moles in 18.0 grams of hydrogen gas, you need to divide the given mass by the molar mass of hydrogen gas. The molar mass of hydrogen gas (H2) is about 2.016 grams/mol. So, 18.0 grams / 2.016 grams/mol ≈ 8.93 moles of hydrogen gas.
How many liters of hydrogen gas at STP can be produced with 645 grams of baking soda?
To find the volume of hydrogen gas produced, we first need to convert the mass of baking soda (645g) to moles. Then, using the balanced chemical equation for the reaction, we can determine the moles of hydrogen gas produced. Finally, using the ideal gas law at STP, we can convert the moles of hydrogen gas to liters.
How many moles of water are made from complete reaction of 1.4 moles of hydrogen gas?
For the complete reaction of hydrogen gas ((H_2)), the balanced chemical equation is: (2H_2 + O_2 \rightarrow 2H_2O) This means that 2 moles of hydrogen gas react to produce 2 moles of water. Therefore, 1.4 moles of hydrogen gas will produce 1.4 moles of water.
