Answer is: not enough colorless syrupy liquid.

n (H₂SO₄) = 1,2 mol.

M (H₂SO₄) = 2Ar (H) + Ar (S) + 4Ar (O) · g/mol.

M (H₂SO₄) = 2·1 + 32 + 4·16 · g/mol.

M (H₂SO₄) = 98 g/mol.

m (H₂SO₄) = n (H₂SO₄) · M (H₂SO₄).

m (H₂SO₄) = 1,2 mol · 98 g/mol.

m (H₂SO₄) = 117,6 g needed.

100 g is less that 117,6 g.
