## How many grams are in 5 moles of H2O?

Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of **90.05 g**.

## How many mole is in a gram?

The mass of one mole of a substance is equal to **that substance’s molecular weight**. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## What does 1 mole H2O mean?

Explanation. A mole is a unit measuring the quantity of anything. Water (H_{2}O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be **2 moles of hydrogen atoms plus 1 mole of oxygen atoms**. weight of water = 2(1.0079) g + 15.9994 g.

## How many moles are in H2O?

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. Notice that the molar mass and the formula mass are numerically the same.

## How many grams is 5.5 moles of water?

Well, ONE mole of water has a mass of 18.01⋅g⋅mol−1 … amd 5.5⋅mol has a mass of approx.**.** **99⋅g** ..

## How many grams are in 3 moles of water?

similarly 1 mole of water is equivalent to molecular mass of water x 3 that is 18×3=**54 gram**.

## How many moles are in 5g of water?

**5/18 moles** for 5 grams of water.

## How many moles are in 36.0 g of H2O?

Hence, the number of moles in $36g$ of water is **two moles**.

## How many moles are in 100g?

There are **5.55 moles** of water in 100g of it.

## How many moles are in 45 grams?

45 grams silver X (1 mole / 107.87 grams) = **0.417 moles**.
