How many molecules of water are in one drop if there are 3.44×1022 molecules in 1.00 g (given that 1 mL = 20 drops)? Assume that 1 mL = 20 drops is an exact equivalent and does not affect the number of significant digits in the answer. (Assume density of water is 1.00 g/mL.)

The covalent compound acetylene, which is the fuel of the oxyacetylene torch used by welders, has the molecular formula c2h2. the covalent compound benzene, a commercial solvent, has the molecular formula c6h6 each of these covalent compounds contains carbon and hydrogen atoms in a one-to-one ratio. would it be correct to write the chemical formulas of each as ch? explain.
