How many molecules of carbon dioxide are in 243.6 g of carbon dioxide
1 answer:
Answer:
Explanation:
First, lets find the molar mass of CO². This is approximately 12 + 2(16) = 44 g/mol. Now, let's set up the conversions.
This is Avogadro's number
↓
243.6g CO² * (1 mol CO² /44g CO²) * (6.023 * 10^23 molecules/ 1 mol)
When we cancel out the units, we are left with 3.33 * 10^23 molecules of carbon dioxide. I hope this makes sense!

It takes up space/ the rest do not
Li2S + 2 HNO3 --> 2 LiNO3 + H2S
Li2 S + H2 N2 O2 --> Li2 N2 O5 + H2 S
Li S + H2 N2 O5 -> Li N2 O5 + H2 S
Li2 S2 + H4 N4 O10 --> Li2 N4 O10 + H4 S2
Li^2 S^2 + H^4 N^4 O^10 --> Li^2 N^4 O^10 + H^4 S^2
D. due to the the water it will bring sand with the water there for us is D.
I believe the correct answer is 2340g of a particular substance will be dissolved in 650 L of H2O. Hope I was helpful in some way. Thanks. Peace.
1 mol of any particles = 6.02*10²³ particles
56 mol*6.02*10²³ molecules of water/1 mol =3.37*10²⁵
