## 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.

- The formula for the number of moles formula is expressed as.
- Given.
- Number of moles formula is.
- Number of moles = Mass of substance / Mass of one mole.
- 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.
