Question

The number of particles in 0.5 moles Of a substance is..?​

Answer 1

A mole is about 6.022 * 10^23 of anything. So half a mole of water molecules is 3.011 * 10^23 molecules of water. 0.5 x 6.022 x 10^23 molecules of water

Answer 2

1 mole = 6.022 × 10^23 particles

0.5 mole = 0.5 * 6.022 × 10^23 or (6.022 × 10^23)/2 particles

               = 3.011 × 10^23 particles
