Question

Calculate the number of molecule present in 0.5 mole of water.​

Answer 1

$\huge{\mathcal{\blue{\underline{Answer}}}}$

$1mole \: = 6.022 \times 10 {}^{23} molecules$

Hence ;

$0.5mole = 0.5 \times 6.022 \times 10 {}^{23} \\ = 3.011 \times 10 {}^{23} molecules$

Answer 2

Answer:

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.
