# Frequent question: How many moles of water is present in a 5g of water drop?

Contents

One mole of water is 18.016 grams, so in 0.05 grams, in one drop, the number of moles is: moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles.

## How many moles are in 5g?

Moles = mass / molar mass

So, 0.125 moles are present in 5g of NaOH.

## How many moles are in 5 mL of water?

, Former Mathematics teacher and ongoing tutor. The molecular weight of water is 18.0152 grams/mole. A ml of water at STP weighs 1 gram therefore 5 ml would weigh 5 grams.

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

Answer: 0.2 mole of oxygen atoms = 16 × 0.2 = 3.2 g (b) 1 mole of water molecules = 18 g ∴ 0.5 mole of water molecules = 18 × 0.5 = 9 g 10.

## How many moles of water are in 1 grams of water?

The average mass of one H2O molecule is 18.02 amu. 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 many moles is 135g of water?

There are 0.015 moles of hydrogen (H) in 135 mg of H2 O. To find this, we first need to convert the mg to grams.

## How many moles of h2o are present in 36 g of water?

Hence, the number of moles in \$36g\$ of water is two moles.

## 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.

## How do you calculate moles of water?

Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. On adding all the above-obtained values we get, Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

## How many grams is 5 moles of water?

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 5 moles 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.

## How many g of H2O are present in 0.25 mole?

1 mole of water weighs equal to the molecular mass of water. Thus the amount of present in 0.25 mole of it​ is 4.5 grams.

## How many molecules are in 5g of water?

Therefore molecular mass of water (M) is equal to 18,01. So in 5g sample of water there is 1.67 x 1023 water molecules.

## How many moles of water are in 50g of water H2O?

Water or H2O has a Molar Mass of about 18.02 g/mol. n= 2.77 moles of water in a 50 gram sample.

## How many moles of water are in 50g of water?

There are 3 moles of O in 50 g.
