# How many moles are in 16g of he?

## How many moles are in 16g of he?

16/4 moles
The correct answer is 24.09 × 1023. 1 mole helium = 6.023 x 1023 atoms. 1 mole helium = 4g. So, 16 g helium = 16/4 moles = 4 moles.

### How many moles of helium are in a gram?

If we look this number up for helium, we find that helium has a molar mass of 4.0 grams per mole. So one mole of helium has a mass of 4.0 grams. We can use the molar mass as a conversion factor. Two moles of helium times four grams of helium per mole of helium is equal to eight grams of helium.

How many moles are there in 16 gram of water?

16g of water is equal to 8/9 or 0.88.. moles.

How do you find moles from grams of an element?

Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass.

## How many grams are in 12 moles of he?

Just under 50⋅g .

### How many moles are in 4 moles of he?

Answer: 1 mole of Helium = weight of helium/4weight of helium= 1*4=4 grams 1 mole of Helium contains 6.023*10>23 (Avogadro Number)atoms.

How many moles are in 20 grams?

There are 5.00 moles He in 20.0 g He.

How many moles are in 12 grams?

The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Helium, or 4.002602 grams.

## How many moles are in H2O?

one mole
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. Notice that the molar mass and the formula mass are numerically the same.

### 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 I calculate moles?

The unit is denoted by mol.

1. The formula for the number of moles formula is expressed as.
2. Given.
3. Number of moles formula is.
4. Number of moles = Mass of substance / Mass of one mole.
5. Number of moles = 95 / 86.94.

How many grams is a mole?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
