Just look up the word on google and it will tell u
Answer:
46.76 g
Explanation:
The reaction that takes place is:
First we <u>determine the limiting reactant</u>:
1.3 moles of SiO₂ would react completely with (3 * 1.3) 3.9 moles of C. There are not as many C moles, meaning that C is the limiting reactant.
Now we<u> convert C moles (the limiting reactant) into CO moles</u>, using <em>the stoichiometric coefficients</em>:
- 2.5 mol C * = 1.67 mol CO
Finally we <u>convert 1.67 moles of CO to gram</u>s, using its <em>molar mass</em>:
- 1.67 mol CO * 28 g/mol = 46.76 g
