**What does 1 mole of h2o weigh?**

The average mass of **one H2O molecule is** 18.02 amu. The number of atoms **is** an exact number, the number of **mole is** an exact number; they **do** not affect the number of significant figures. The average mass of **one mole of H2O is** 18.02 grams. This **is** stated: the molar mass of water **is** 18.02 g/**mol**.

Besides, how much does a mole of h2o weigh?

18.01528 g/mol

Likewise, how do you find the mass of one mole of h2o? **H2O** =(**1**×2) +16 = 18 a.m.u. 18 amu is the **mass of one molecule** of water. 18 gm per mol is the **mass of one mole** of water.

Also to know, what does 1 mole of water weigh?

A **mole is** a convenient counting unit whenever **one is** dealing with numbers of atoms or molecules. It **is** equal to Avogadro’s number (NA), namely 6.022 x1023. If we have **one mole of water**, then we know that it **will** have a mass of 2 grams (for 2 **moles** of H atoms) + 16 grams (for **one mole** O atom) = 18 grams.

How do you calculate the weight of water?

To find the **weight of water**, start by finding the density(1 kg/L at 39.2°) and the volume of **water**. Convert the volume of **water** to liters and then multiply by the density to find the **weight**.
