Please answer these questions on your Page 6
(a)
The percent composition of an unknown substance is 46.43% C, 25.77% O, 18.05% N, and
9.74% H. What is its empirical formula? The molar masses of C, O, N, and H are 12.01, 16.00, 14.01,
and 1.01 g/mol.
(b)
What total mass of CO₂(g) and H₂O(1) is produced by the complete combustion (the
reaction with O₂(g) to produce these two products) of 44.4 g of C4H₁0O(1)? The molar masses of C,
O, and H are 12.01, 16.00, and 1.01 g/mol.
