What is the mass of 5 5 moles of Fe2O3?

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.

THIS MEANING:  How long do red acne marks take to fade?

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.
