Hello,
I am doing some experiments with measuring the amount of hydrogen produced from a combination of NaBH4 and water. I know the theoretical maximum mass of gas produced but, when measured, the total mass loss due to the gas evaporating is 3-4 times the theoretical maximum. I believe water is evaporating and this is causing the increased mass loss. Can anyone give me any suggestions on how to either calculate or estimate the water evaporation in order to find the mass of hydrogen produced? Thank you
