Idk but I’ll try to answer
Answer:
The answer to your question is 6
Explanation:
Data
Cu + 2AgNO₃ ⇒
To find the answer, count the number of each element in the reactants
Element Quantity
Copper 1
Silver 2
Nitrogen 1
Oxygen 6
Then, in the products, there must be 6 oxygens so in the products there must be 6 oxygens so the reaction is balanced.
Hydrogen - 7.44%
Carbon - (100-7.44)% = 92.56%
Lets take 100 g of benzene, then we have
Hydrogen - 7.44 g
Carbon - 92.56 g
n - number of moles
n(H) = 7.44g *1 mol/1.0g = 7.44 mol
n(C) = 92.56 g* 1mol/12.0 g ≈ 7.713 mol
n(C) : n(H) = 7.713 mol : 7.44 mol = 1:1
Empirical formula is CH.
M(CH) = (12.0+ 1.00) g/mol = 13.0 g/mol
M (benzene) = 78.1 g/mol
M (benzene)/M(CH)= 78.1 g/mol/13.0 g/mol = 6
So, molecular formula of benzene is C6H6.
