## How many moles are in 50 grams?

To calculate the weight of an element in grams to moles, we should know the molar mass of an element. For example, 50 grams of oxygen is equal to **3 moles**.

## How many moles are in 100g of ethanol?

**2.173 moles** of ethanol are present in a 100.0 g sample of ethanol. Explanation: The ‘amount of substance’ that contains as ‘many particles’ as there are atoms in exactly ’12 g of Carbon’- 12 isotope is called one mole.

## How do you calculate moles from 50?

So in order to calculate the number of moles of any substance present in the sample, we simply **divide the given weight of the substance by its molar mass**. Where ‘n’ is the number of moles, ‘m’ is the given mass and ‘M’ is the molar mass.

## How many moles of water is 50grams?

There are **3 moles** of O in 50 g.

## How many moles are there in 4.50 g of ethanol?

That gives us 45 over 18.02 and that’s equal to **2.50**.

## How many moles of atoms are in ethanol?

Because **1 mol** of ethanol contains 2 mol of carbon atoms (2 × 12.011 g), 6 mol of hydrogen atoms (6 × 1.0079 g), and 1 mol of oxygen atoms (1 × 15.9994 g), its molar mass is 46.069 g/mol.
