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

## What is the mass of 10 moles of H2O?

10=m/18. Therefore,Mass of 10 moles of water =10×18=180 g.

## What is the mass of 2.0 moles of water?

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.

## What is the mass of 5 moles of water?

5 mole of water =0. 5×18 =9gm.

## How many moles are in 8 grams of CO2?

We assume you are converting between moles CO2 and gram. You can view more details on each measurement unit: molecular weight of CO2 or grams This compound is also known as Carbon Dioxide. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles CO2, or 44.0095 grams.

## What is the mole of H2O?

Average atomic mass of O: 16.00 g/mol. 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.

## How do you convert moles of water to mass?

A substance’s molar mass is calculated by multiplying its relative atomic mass by the molar mass constant (1 g/mol). The molar mass constant can be used to convert mass to moles. By multiplying a given mass by the molar mass, the amount of moles of the substance can be calculated.

## How do u calculate mass?

Divide the object’s weight by the acceleration of gravity to find the mass. You’ll need to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you’re measuring the mass of an object on Earth, divide the weight in Newtons by the acceleration of gravity on Earth (9.8 meters/second2) to get mass.

## How many grams are in 2 moles?

The answer is 0.0087094358027487. We assume you are converting between moles In and gram. You can view more details on each measurement unit: molecular weight of In or grams The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles In, or 114.818 grams.

## What is the mass of 5 mole of H2O?

Five moles of water whould have a mass of 90.05 g. One molecule of water weighs 18 AMU. If the number of water molecules is Avogadro’s number, it would be one mole of water.

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

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.

## What is the mass of 0.5 moles of water H2O?

Thus, the mass of 1 mole of water is 18 grams. Thus, the mass of 0.5 mole of water (H2O) is 9 grams.

## What is the weight of 12 moles of water?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Water, or 18.01528 grams.

## How many moles of water are in a cup?

1 cup is approximately 250ml (i.e. 250cc) – so 1 cup will contain approximately 13.89 moles of water, which will contain approximately 8.36 x 1024 molecules of water.

## How many moles of water are in the sample?

The molar mass of water (H2O H 2 O ) can be obtained by adding up the atomic masses of two hydrogens and one oxygen (18.02 g/mol). These can be obtained from a periodic table. Therefore there are 3.32 mol of water in the sample.
