Answer:
0.852 mol
Explanation:
First we <u>convert 4.00 g of helium (He) into moles</u>, using its <em>molar mass</em>:
4.00 g ÷ 2 g/mol = 2 mol He
To answer this problem we can use<em> Avogadro's law</em>, which states that at constant pressure and temperature:
V₁n₂=V₂n₁
Where:
We <u>input the data</u>:
- 24.4 L * n₂ = 10.4 L * 2 mol
And <u>solve for n₂</u>:

Answer:
Energy cannot be converted from one form to another.
Answer: 2.54g
Explanation:
Molar Mass of H2O2 = (2x1) + (2x16) = 34g/mol
1mole (34g) of H2O2 contains 6.02x10^23 molecules
Therefore Xg of H2O2 will contain 4.5x10^22 molecules i.e
Xg of H2O2 = (34x4.5x10^22)/6.02x10^23 = 2.54g
