Answer:(3)
Explanation: 2Al+3H2SO4----->Al(2SO4)3+3H2
For this item, we find first the mass of the compound with the empirical formula. That is,
molar mass = 12 (for C) + 1 (for H)
= 13 g/mole
Then, we divide the given mass of the molecular formula by the mass of the empirical formula.
n = 52.07 / 13 = 4
Therefore, the molecular formula is C₄H₄.
I think the answer is A. 28 because you add 27 + 1 = 28 and add the 13AL and makes 2813AL
