The mass (m) of Fe is: [55.9 g/mol × 4.50 moles] = 251.6 grams.

## What is the mass of 4.20 moles of Fe?

Answer. 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. So, the result will be 235g Fe.

## How many grams are in a mole of Fe?

## How many moles of boron is 1.00 grams?

The SI base unit for amount of substance is the mole. 1 grams Boron is equal to 0.092498381278328 mole.

## What is the relationship between moles and mass?

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.

## What is the formula for calculating moles?

Chemical Reactions and Masses of Reactants and Products

- mass O2 = moles(O2) × molar mass(O2) (a) Calculate moles Mg = mass(Mg) ÷ molar mass(Mg) moles(Mg) = m ÷ 24.31. …
- mass MgO = moles(MgO) × molar mass(MgO) (a) Calculate moles Mg = mass(Mg) ÷ molar mass(Mg) moles(Mg) = m ÷ 24.31.

## What is the formula to find the mass?

mass=density×volume (m=ρV).

Density is a measure of mass per unit of volume, so the mass of an object can be determined by multiplying density by volume.

## How do you find how many grams are in a mole?

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. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles.

## What is the unit of molar mass?
