## What is the mass of 4 mol of Fe atoms?

If you look into your periodic table, the molar mass of Fe is 55.9 g/mol. The mass (m) of Fe is: [55.9 g/mol × 4.50 moles] = 251.6 grams.

## What is the mass of 5 moles of iron?

5 moles of Fe weigh=55.845/1 x 5=279.225g.

## How much does 1 mole iron weigh?

The atomic mass is useful in chemistry when it is paired with the mole concept: the atomic mass of an element, measured in amu, is the same as the mass in grams of one mole of an element. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.

## What is the mass of 5 moles of Fe2O3?

2. What is the mass of 5 moles of Fe2O3 ? Smal x 159.0 1798.45g Page 2 3.

## What is the mass of 5 moles of water?

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 do I calculate moles?

1. First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
2. For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.

## How many h2o molecules are in a mole?
