To determine the number of dna molecules that can be stacked as requested in this item, we convert the given measurements in a single unit. For simplicity, we convert all the lengths to meters.

Length of DNA molecule = (2.5 nm) (1 x 10^-9 m/1 nm) = 2.5 x 10^-9 nm

Height of a person = (5 ft 10 in) (12 inches / 1ft) (2.54 cm/1 in) (1 x 10^-2 m / 1 cm)

= 1.778 m

Then, divide the height of the person by the length of a single DNA molecule.

n = 1.778 m / (2.5 x 10^-9)

n = 7.112 x 10^8

Hence, the number of DNA would be 7.112 x 10^9.
