You should do which candle burn the fastest colored or white
Answer:
39
Explanation:
Electrons weigh almost nothing, so their mass doesn't really matter for these types of problems. Just subtract 118-79 to find the remaining mass which is for the neutrons.
First you need to know how many moles you would get from 165 g of carbon dioxide.
Carbon = 12
Oxygen 2 = 16 x 2 = 32
Total: 32 + 12 = 44
- Use proportions
1 mol CO2 x 1 mol CO2 44 g
---------------- = ---------- or ----------------- = ----------
44 g 165 x 165 g
165/44 = 3.75 moles CO2
- Last step is to multiply the amount of moles by Avagadros number, 6.02 x 10^23
3.75 x 6.02 x 10^23 = 2.25 x 10^24 molecules
- Keep in mind if your answer can be a little different than mind if you either round or keep the same numbers. I hope this Really Helps ! c:
neutrons to the carbon-12 and carbon-14
