Question

Calculate the number of molecules in 1.5 mil of hydrogen chloride, HCl

Answer 1

Answer:

Calculate the number of molecules in 1.5 mil of hydrogen chloride, HCl

no. of moles = 1.5

let no of molecules be x

no of moles molecules

1 mole -------> 6.022 × 10²³

1.5 mole -------> x

by cross multiplication,

1 × x = 6.022 × 10²³ × 1.5

x = 9.033 × 10²³ molecules.

Hence, the number of molecules in 1.5 mil of hydrogen chloride, HCl are 9.033 × 10²³ molecules.
