It will be one mole of water in case the number of water molecules is Avogadro's number as carbon weighs 12 AMU per atom and one mole of carbon weighs 12grams so accordingly, mole of water would weigh 18grams.
And Mass = moles × Mr there will be 90 grams of the substance in 5 moles of water. 02 has 16 argons, hydrogen has Argon of 1. So, 1×16=(02)+1×2=2(h), Mr =18. And 5 moles = 5×18=80 grams.
