20 cups of flour, 30 eggs, and 10 cups of sugar
Answer: 5moles
Explanation:
1mole of a substance contains 6.02x10^23 molecules.
Then, 1mole of CO also contains 6.02x10^23 molecules.
If 1 mole of CO2 contains 6.02x10^23 molecules, it means Xmol of CO contains 3.01 E24 ie 3.01x10^24 molecules
Xmol of CO = 3.01x10^24 / 6.02x10^23
Xmol = 5moles
Answer:
E
