How many moles are equal to 1.27x10^23 molecules of h2o

0.211 moles

Explanation:

From the Question;

Molecules of H₂O = 1.27 × 10^23 molecules

We are required to calculate the number of moles

we need to know that 1 mole of a compound contains a number of molecules equivalent to the Avogadro's constant, 6.022×10^23.Therefore, 1 mole of water, H₂O = 6.022×10^23 Molecules To get the number of moles we divide number of molecules by the Avogadro's number.

Number of moles of water = 1.27 × 10^23 molecules ÷ 6.022 × 10^23 molecules

                                            = 0.211 Moles

Thus, the number of moles of water that are equal to 1.27 × 10^23 molecules is 0.211 moles.
