## What is mole find out the number of moles in 100 g of water?

Number of moles=100g/ 18.02 g/ moles= **5.55 moles**.

## How many h2o molecules are in 100 g of water?

The mols cancel out leaving us with 5.55 * 6.022×10^23 molecules. Which is **~ 3.34×10^23 molecules** of water are produced from 100 grams of water.

## How many moles are in 90 g of h2o?

hence 90 g of H20 contains **5 moles**.

## What is the formula for moles to grams?

In order to convert the moles of a substance to grams, you will need to **multiply the mole value of the substance by its molar mass**.

## What mass of water is produced?

Water has a molar mass of 18 g/mol . So, 24mol ⋅18 g/mol =**432 g** of H2O was produced.

## What is the size of a mole?

Normal moles

A normal mole is usually an evenly colored brown, tan, or black spot on the skin. It can be either flat or raised. It can be round or oval. Moles are **generally less than 6 millimeters (about ¼ inch) across** (about the width of a pencil eraser).

## How many grams are there 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**.

## What is the mass of 5 moles H2O?

Five moles of water whould have a mass of **90.05 g**.

## How many moles are in 90 gram of water?

A mole of a compound is a number of grams equal to the atomic weight of a molecule of the compound, so for water we have 2 hydrogen atoms and one oxygen, so the atomic weight of water is 1+1+16=18, so a mole of water is 18 grams. We have 90g of water so we have 90/18 = **5 moles** of water.

## How many grams are in 2 moles of carbon dioxide?

The weight of CO2 is **44 grams per mole** (1 x 12 grams/mole for the carbon and 2 x 16 grams/mole for the oxygen atoms).

## How many grams are in 2 moles of HF?

Explanation: Normally 1 mole of F2 reacts with 1 mole of H2 giving 2 moles of HF (which is **20g**).
