No. Of moles of ch4 = 100/(12+4) =6.25
No of moles of co2 = 6.25
La materia puede encontrarse en diferentes estados dentro de nuestro planeta: líquido, sólido y gaseoso. Fuera de la Tierra existe un cuarto estado, conocido como plasma, que abunda en lugares como el Sol y las estrellas.
Answer:
2.29 g of N2
Explanation:
We have to start with the <u>chemical reaction</u>:
The next step is to <u>balance the reaction</u>:
We can continue with the <u>mol calculation</u> using the molar mass of
(65 g/mol), so:
Now, with the<u> molar ratio</u> between and we can <u>calculate the moles</u> of (2:3), so:
With the molar mass of we can <u>calculate the grams</u>:
I hope it helps!
Answer:
the ans
Explanation:
Sodium + chlorine → sodium chloride
The balanced chemical equation:
2Na + Cl2 → 2NaCl
According to the equation above: n(Na) = n(NaCl)
Moles of Na = Mass of Na / Molar mass of Na
The molar mass of Na is 22.9898 g mol-1.
Hence,
n(Na) = 86.33 g / 22.9898 g mol-1 = 3.755 mol
n(NaCl) = n(Na) = 3.755 mol
Moles of NaCl = Mass of NaCl / Molar mass of NaCl
Mass of NaCl = Moles of NaCl × Molar mass of NaCl
The molar mass of NaCl is 58.44 g mol-1.
Hence,
m(NaCl) = 3.755 mol × 58.44 g mol-1 = 219.44 g
m(NaCl) = 219.44 g
OR:
(86.33 g Na)×(1 mol Na/22.9898 g Na)×(2 mol NaCl/2 mol Na)×(58.44 g NaCl/1 mol NaCl) = 219.45 g
Answer: 219.44 grams (or 3.755 mol) of sodium chloride (NaCl) will be produced.
