How do you find moles of gas?
Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.
How do you determine molar mass?
Molar mass = mass/mole = g/mol The mass of one mole of carbon-12 atoms is exactly 12 grams; its molar mass is exactly 12 grams per mole.

How do you calculate grams to moles?
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.
How do you convert HBr to Br2?
At Tc = 700 °C around 82.3% HBr is converted to Br2. Below 700 °C, the ratio decreases obviously and at Tc = 300 °C only around 64.2% HBr is converted to Br2. At Tc = 200 °C, around 61.6% HBr is converted to Br2.
How do you find the molar mass of a gas?
The molar mass of a gas can be derived from the ideal gas law, PV=nRT , by using the definition of molar mass to replace n , the number of moles.
What is the molar mass of gas?
The unit that is used to measure the molar mass is grams per moles (g/mol). The mass of gas in a one-mole sample is equal to the molar mass of gas. If the molar mass of gas X was 40 g/mol, this means that the weight of gas X in a one-mole sample is equal to 40 grams.
What is a mole and molar mass?
A mole is 6.02⋅1023 (avogadro's number) molecules of a substance. The molar mass is the amount of mass that 1 mole of that substance possesses.
