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

Chemistry

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!

Plete the following problems significant figures: 6 × 0.30<br>​
jeka57 [31]
6= Only the digits 1 and 6 are the actual measured values. Therefore we have only 2 significant figures.

0.3= Zeros used as placeholders are not significant. Zeros that come before non-zero integers are never significant. Example 5: The zeros in 098, 0.3, and 0.000000000389 are not significant because they are all in front of non-zero integers. c. If the zeros come after non-zero integers and are followed by a decimal point, the zeros are significant.
