## How many molecules are there in 0.5 moles of water?

Answer: A mole is about 6.022 * 10^23 of anything. So half a mole of water molecules is 3.011 * 10^23 molecules of water. 0.5 x **6.022 x 10^23 molecules** of water.

## What is 0.5 mole water?

For 1 mole of water =molecular mass of water (H2O)in grams =mass of 2H atoms +mass of O atoms =2×1+16. =2+16. =18 grams ⇒ for 1 mole. For 0.5 moles = 18×0.5. = **9.0 grams**.

## How do you find the mass of 0.5 moles of water molecules?

**Calculate the mass of.** **0.5 mole of water molecules**

- you are intelligent man. write answer.
- Mass of 1 mole of H2O molecule = (1 x 2 + 16) = 18 u. Mass of 0.5 mole of H2O molecule = (18 x 0.5) u =9 u.

## What is the mass of 5 mole of water molecules?

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 molecules are there in 0.5 mol of co2?

since 1 mol represents 6.02 x 10^23 particles, there are **0.5×6.** **02×10^23 particles** (molecules) of carbon dioxide.

## What is the number of molecules in 0.25 mole of oxygen?

0.25 moles of oxygen there is **6.023/4×10^23 molecules**.

## 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 is the mass of 0.5 mole of ammonia and water?

Hence the mass of 0.5 moles of NH3 = 17/2 u (OR) **8.5 u**.

## What is the mass of 0.5 mole of S?

Step-by-step explanation:

One mole of sulphur contains 32 amu. so 0.5 mole will have **16 amu**.

## How many number of molecules are there in 22g of co2?

6.02*10^23 molecules equals 1 mole.

## How many moles are in 90 grams 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.

## What is the mass of 10 mole H2O?

So, 10 mole of water will weigh (18×10) = **180g**.

## How many moles are present in 2.3 gram of any?

Solution: Molecular mass of Sodium is 23 u. So, 23 g of sodium is equal to 1 mole. The number of mole in 2.3 g = 2.3 / 23 = **0.1 mole**.
