The answer is:
1. 500g stainless steel cup
<span>2. 500g aluminum cup </span>
<span>3. 750g aluminum cup</span>
I believe that the answer is 12 because there is already 3 O molecules and since its in parentheses with 3 outside it that means that there are 3 of those CO molecules meaning that for every 1 CO there will be 3 O’s so 3, four times Is 12
Answer:
91%
Explanation:
Since you are just trying to find the yield, take the moles of the substance from the products and divide it by the mol value of the reactants. Multiply by 100 to find percentage
0.45 ÷ 0.41 = 0.91111...
91%
