Question

How many moles are in 14.35 x 1022 molecules of H3PO4?

Answer 1

0.24mole

Step-by-step explanation:

Given parameters:

Number of molecules = 14.35 x 10²² molecules;

Unknown = number of moles of H₃PO₄

A mole of a substance is the quantity of matter that contains the avogadro's number of particles.

This number is given as 6.02 x 10²³ particles. The particles can be atoms, molecules, protons, electrons e.t.c

6.02 x 10²³ molecules is contained in 1 mole of any substance

14.35 x 10²² molecules will contain:
`(1.435 x 10^(23) )/(6.02 x 10^(23) )` = 0.24mole
