A mole is 6.022×1023 of anything, including atoms. So to determine the number of atoms are in 30 moles of iron, you multiply the number of moles times 6.022×1023.
30mol Fe x 6.022×1023 atoms Fe/1mol Fe = 1.8066×1025atoms Fe
When corrected for significant figures, the answer is 2×1025atoms Fe.
Note: the number following the 10 in the large numbers is the exponent on the 10 and should be written as superscripts, but that is not supported at the moment.

How many moles of Fe are present in 30 grams in rust?
This amount may be different because rust is not a clearly definite compound.
Calculate the amount of CO2 in the moles that forms if 10 mol of c3h4 react according to the following balanced equation c3h4 4o2-3co2 2h2o?
From the balanced equation, we can see that 3 moles of CO2 are formed for every 1 mole of C3H4 that reacts. Therefore, if 10 moles of C3H4 react, 30 moles of CO2 would be formed (10 moles C3H4 x 3 moles CO2/1 mole C3H4).
How many moles of Cl are in a sample that contains 10.0 moles C2HCl3?
it wouldn't be moles of Cl it would be Cl2 as chlorine doesn't exist as an atom it exsists as two joined to form a compound this is very easy stuff the answer is 15 moles of Cl2 as there 30 moles of Cl hope this helps learn your moles it's easy stuff
How many moles of silver atoms are in 1.8 x 10 25 atoms of silver?
To calculate the number of moles, you divide the number of atoms by Avogadro's number (6.022 x 10^23). So for 1.8 x 10^25 atoms of silver, the number of moles would be 30 moles.
How many atoms of iron are there in 30g bowlof cornflakes that contains 0.0024g iron per 30g serving?
To calculate the number of iron atoms in the 30g serving of cornflakes, first determine the number of moles of iron in the serving using the molar mass of iron (55.85 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of iron atoms in the serving.

If 10 moles of A3 are reacted with excess B2 how many moles of AB will be produced 2A3 plus 3B2 6AB?
From the balanced equation, 2 moles of A3 react with 3 moles of B2 to produce 6 moles of AB. Therefore, if 10 moles of A3 are reacted, the ratio of moles of AB produced would be (10 moles A3 / 2 moles A3) * 6 moles AB = 30 moles AB.
2A3 plus 3B2 6AB If 10 moles of A3 are reacted with excess B2 how many moles of AB will be produced?
For every 2 moles of A3, 3 moles of B2 react to form 6 moles of AB. Since we have 10 moles of A3, we need to double the moles of B2 reacting, which would be 15 moles of B2 to fully react with the 10 moles of A3. This would produce 30 moles of AB.
