At 280 K carbon dioxide is a gas and formic acid is liquid.

Dipole dipole is strong enough to keep the molecules in contact with each other, making  formic acid a liquid at 280K. The attraction between molecules of CO2 is substantially weaker, so this compound is a gas.

Why is acetic acid more soluble than benzoic acid in water? (Hint: What structural features does a molecule need to able to be soluble in water? Refer to relevant intermolecular forces.)

Because phenyl group in benzoic acid is much less polar then methyl in acetic acid. The more substance is polar, the more its solubility.

The complete combustion of heptane (C7H16) in oxygen produces carbon dioxide and water. If I had 4.75g of heptane and combusted this to completion, how many grams of carbon dioxide would I produce?

100 gm of heptane will form 308 gm of carbon dioxide.So 4.75 gm of heptane will form 14.63 gm of carbon dioxide14.63 gm of CO2 will be produced
