Answer:
52.0 g of LiCl represents 1.23 moles of compound
Explanation:
In order to determine the moles of LiCl, we need to know the molar mass of our compound
Molar mass LiCl = Molar mass Li + Molar mass Cl
Molar mass LiCl = 6.94 g/mol + 35.45 g/mol =42.39 g/mol
Now, we can do the conversion:
52 g . 1 mol / 42.39 g/mol = 1.23 moles
Correct Answer: option 1 i.e. C
Reason:
The the compound of interest i.e. XCl4, since there are 4 Cl atoms bonded to X. This signifies that the valency of X is 4.
There atomic number of C is 6. It's electronic configuration is giving by 1s2 2s2 2p2. Thus, there are 4 electrons in valence shell of C. This signifies that valency of C is 4. Hence the compound present in present case is CCl4.
10. is C or gas and 11. is B liquid.
