Question

What does one mole of H2O correspond to? 6.02 × 1023 molecules of H2O 6.02 × 1023 atoms of H and 6.02 X 1023 atoms of O 6.02 × 1023 atoms of O 6.02 × 1023 atoms of H 6.02 × 1023 × 2 atoms of H

Answer 1

C. 6.02x10^23 atoms of O

Step-by-step explanation:

There are two atoms of Hydrogen

Answer 2

1 mole of any substance corresponds to a special number called "Avogadro's Number" (6.022×10²³ (atoms, molecules, ions) ). The units of this number vary depending upon circumstance. In this problem for example, you are asked about a mole of
`H_(2) O` which is a molecule. Therefore, your units must be molecules rather than atoms or ions.

Answer:
There are 6.022×10²³ molecules of
`H_(2) O` in 1 mole of
`H_(2) O`.
