Question

How many molecules are in 2.50 moles of h2o

Answer 1

To find out how many molecules you have, you need to multiply the number of moles with Avogadros constant: 2.50 * 6.022 * 10²³ = 1.5055 * 10^24.

Answer 2

Step-by-step explanation:

According to the mole concept there are
`6.022 * 10^(23)` atoms or molecules are present in 1 mole of a substance.

Mathematically, 1 mole =
`6.022 * 10^(23)` atoms or molecules

Therefore, calculate the number of molecules present in 2.50 moles of
`H_(2)O` as follows.

`2.50 mol * 6.022 * 10^(23)}molecules/mol`

=
`15.055 * 10^(23)` molecules

Thus, we can conclude that there are
`15.055 * 10^(23)` molecules in 2.50 moles of
`H_(2)O`.
