Can someone help me understand how to solve mole problems in chemistry?
2 answers:
<span>I start the reaction below with 1.5g of Al, how many moles of Cl can I make" (Al + Cl2 ➡ NaCl)
First thing to do is find out what the amu of Al is.
You can find that on a periodic table. 26.98grams per mole
1.5g Al x </span>
= <span>0.05559673832 = 0.056 moles of Al
Now ratio the moles.
0.056 moles Al x </span>
= 0.056 moles of Cl
The answer is 0.056 moles of Cl
First thing to do is find out what the amu of Al is.
You can find that on a periodic table. 26.98grams per mole
1.5g Al x </span>
Now ratio the moles.
0.056 moles Al x </span>
