# Question: What is the mass in grams of 3 moles of water molecules?

Contents

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

## How many molecules are in 3 moles h2o?

How many water molecules are in 3 moles of water molecules? So, in 3 moles of the substance, there’ll be 3⋅6=18 moles of water molecules. Remember that a mole of molecules contains 6.02⋅1023 molecules. So here, there’ll be a total of 6.02⋅1023⋅18≈1.08⋅1025 water molecules.

## What is the mass in grams of 3 moles of?

Mass of 3 moles of n is 42.0201g.

## What is the mass of 2 moles of water molecules?

One mole of water has a molecular mass of 18 grams. Two moles of water have a molecular mass of 18×2=36 grams. Thus the molecular mass of two moles of water is 36 grams.

## How many molecules are there in h20?

One mole of water has a mass of 18 grams and a volume of 18 mL (as the density of water is 1 g per cm3). It contains Avogadro’s number of molecules (6x 10^23). Thus 1 litre of water contains 1 / 18 x 1000 x 6 x 1^23 molecules (assume you can do the maths…)

## How many atoms are in 3.00 moles water?

As you can see 1 H2O molecule contains 3atoms. Then 6.02×10^23molecules will contain 3 × 6.02×10^23 atoms.

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

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

## What is the moles of water?

One mole of water is about 18 milliliters.

This is the volume of a few drops of water, 3.65 teaspoons, 1.2 tablespoons, or 0.018 liters. It’s not a large volume, yet it contains 6.022 x 1023 water molecules! You can use the same steps to find the mass and volume of any other substance.

## What is the mass of 3 moles of neon?

We know, molar mass of neon ( mass of one mole of neon) = 20 gram. Hence, mass of 3 mole of neon = 3 × 20 = 60 gram.

## What is the mass in grams of 3 moles of oxygen atoms?

3 moles of Oxygen atoms weigh 48.00 grams.

## What is the mass in grams of 3 moles of zinc?

That means that one mole of zinc weighs 65.38 grams (65.38 g/mol). Based on that information, to convert 3 moles of zinc to grams, we multiply 3 moles of zinc by 65.38.

## How many grams is 2.20 moles of water?

1 mole of oxygen atoms got 16 grams. Therefore, 1 mole of H2O got 18 grams. 2 moles of H2O gets you 36 grams.

## What is the mass of 2.5 mole of water?

The amount of oxygen in 2.5 moles of water is 40 grams. The molecular formula of water is H₂O. 1 mole of water contains 1 mole of oxygen.
