## How many moles are in 3.6 g of H2O?

Hence, 3.6g of water contain **0.2 moles** of water.

## What is the mass of 3.5 moles of water?

The mass of water is 3.5 moles*18g/mole=**63g**.

## How many grams are in 3.5 moles?

The mass of 3.5 moles of Ca is **140 g** to two significant figures.

## How many moles are in water?

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 moles of water are in 360 g of water?

(ii) From point, 1 mole of water = molar mass of water =18g **20 moles** of water = 18 g x 20 = 360g (iv) From point, 6.022 x 1023 molecules of water = 1 mole = 18g of water 1.2044 x 1025 molecules of water Therefore, points (ii) and (iv) represent 360 g of water.

## How many moles are 36g of water?

Complete step by step answer:

One can calculate the number of moles in a substance using the above formula. Hence, the number of moles in 36g of water is **two moles**. .

## How many grams is 5 moles of water?

Answer: 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**.

## What is the mass of 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 grams are in 2 moles of H2O?

One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = **2 g/mol**.
