`I have some aliens in my basement who have developed a chemical weapon in an attempt to escape. I was able to survive the first

attack and capture a sample of the dangerous gas. I analyzed it to find that it had a molar mass of 648.52 grams, and its empirical formula is C5H11N2O2P. What is its molecular formula?
A C10H22N4O4P2
B C5H11N2O2P
C C20H44N8O8P4
D CH2.2N0.4O0.4P0.2
E cannot be determined from the information given

bogdanovich [222]

Answer is: 8568.71 of baking soda.

Balanced chemical reaction: H₂SO₄ + 2NaHCO₃ → Na₂SO₄ + 2CO₂ + 2H₂O.

V(H₂SO₄) = 17 L; volume of the sulfuric acid.

c(H₂SO₄) = 3.0 M, molarity of sulfuric acid.

n(H₂SO₄) = V(H₂SO₄) · c(H₂SO₄).

n(H₂SO₄) = 17 L · 3 mol/L.

n(H₂SO₄) = 51 mol; amount of sulfuric acid.

From balanced chemical reaction: n(H₂SO₄) : n(NaHCO₃) = 1 :2.

n(NaHCO₃) = 2 · 51 mol.

n(NaHCO₃) = 102 mol, amount of baking soda.

m(NaHCO₃) = n(NaHCO₃) · M(NaHCO₃).

m(NaHCO₃) = 102 mol · 84.007 g/mol.

m(NaHCO₃) = 8568.714 g; mass of baking soda.
