## What is the mass of 5 moles of?

The mass of 1 mole of any substance is equal to that substance’s molecular weight. Thus we can say that each mole of \$S{O_2} \$ weighs 64 grams. Therefore the mass of 5 moles of \$S{O_2} \$ is 320 grams.

## How many grams is 0.5 moles of Fe2O3?

Since there are 2 Iron and 3 Oxygen, the molar mass of Fe2O3 is: [ 2×55.9+3×16.0 ] = 159.8 g/mol. Therefore the mass of Fe2O3 is: [m = 159.8 g/mol × 0.500 moles] = 79.9 grams.

## What is the formula for moles to grams?

Moles to grams example problem

Solution: Find out the molar mass of the substance (hint: you can use Molar mass of the substance alone to calculate molar mass). The molar mass of KClO3 is 122.548 g/mol. Multiply the given number of moles (2.50 mol) by the molar mass (122.548 g/mol) to get the grams.

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

What is the mass of 5 moles of Fe2O3? 1st find Molar Mass of fe 02 Fe = (55.85)/2) = 111.7g Total = 159.78] Smol l 159.79 rezoz – 799 Garans Poon BO=(16Y3) – 489 Timol = 798.5 3.

## What is the mass in grams of 5 moles of Na?

Mass of sodium is 23 grams. So the total mass of 5 moles of sodium will be 5×23=165 .

## What is the mass of 5 moles of N na2co3?

We know that 1 mole of sodium carbonate weighs 106g. Hence, 5 moles of sodium carbonate weigh 530 grams.

## What is the number of moles equal to?

One mole (abbreviated mol) is equal to 6.022×1023 molecular entities (Avogadro’s number), and each element has a different molar mass depending on the weight of 6.022×1023 of its atoms (1 mole). The molar mass of any element can be determined by finding the atomic mass of the element on the periodic table.

## How many moles are in fe3+?

Ernest Z. The molar mass of Fe³⁺ is 55.845 g/mol. The only difference between an Fe atom and an Fe³⁺ ion is three electrons.
