How many grams of Fe2O3 will be produced from 37.5 grams of iron

Chemistry
1 answer:
Harman [31]3 years ago
3 0

Step 1 : Convert mass of Iron to moles using n = m/MM.

n(Fe) = 37.5 ÷ 55.845 = 0.671501... mol

Step 2 : Using stoichiometric ratios, find how many moles of Fe2O3 are produced.

Fe : Fe2O3 is 4:2, or simply 2:1. For every 2 moles of Fe there is Fe2O3.

Therefore, moles of Fe2O3 is half the amount of Fe!

n(Fe2O3) = 0.5 x 0.671501... = 0.33575... mol

Step 3: Convert the moles of Fe2CO3 to mass using m = n x MM.

m(Fe2O3) = 0.33575... x [2(55.845)+3(15.999)] = 53.61502... grams

Final step: round your answer to the lowest signficant figures. Since you gave me the mass of iron to 3s.f, m(Fe2O3) = <u><em>53.6 grams</em></u> (3s.f) !

Let me know if you're confused in any way!

Calculate each of the following quantities:<br> (a) Total number of ions in 38.1 g of SrF₂
adelina 88 [10]

The total number of ions in 38.1 g of SrF₂ is 5.479 x 10²³.

<h3>What are ions?</h3>

Ions are the elements with a charge on them. It happens when they share electrons with other atoms to form a compound.

We have to calculate the total number of ions in 38.1 g of .

The molar mass of SrF₂ = 125.62 g/mol

The number of moles = 38.1 g of  1.0 mol / 125.62  = 0.30329 moles

Given that, total moles of SrF₂ ions in  = 1.0 mol of + 2.0 moles of  = 3.0 moles

Total moles of ions in 0.30329 moles of

= (0.30329 moles of SrF₂) x 3.0 / 1.0  = 0.90988 mol ions

We know that,

1.0 mole of ions = 6.023 x 10²³ ions

Thus, the number of total ions = ( 0.90988 mol ions) x  6.023 x 10²³ / 1.0 mol = 5.479 x 10²³ ions

Thus, the number of ions is in 38.1 g of 5.479 x 10²³ ions

Jonathan claims that since only humans can read, it must be an inherited trait, passed from human parents to their children. Is
Crank
Jonathan is not correct because it has to be a trait that is learned.

So in that case Jonathan has to say that this is not an inherited trait it is learned by most people.
