A mole is a convenient counting unit whenever one is dealing with numbers of atoms or molecules. It is equal to Avogadro's number (NA), namely 6.022 x1023. If we have one mole of water, then we know that it will have a mass of 2 grams (for 2 moles of H atoms) + 16 grams (for one mole O atom) = 18 grams. Hope it's helpful. plz mark as the brainleast answer..

so i didnt get it...
3×10^-23 gm
ohh
can u pls explain me how it came
????
the question will be 1 mole of h2o
may be... but here it is printed that it is mass of 1 molecule of h2o
ok
it can be a printing mistake
i dont know

the molecular mass of h2o is:
1×2+16=18.
the mass of hydrogen is 1 and oxygen is 16.
1 molecule of water=18/6.022×10^23
=2.99×10^-23
1×2+16=18.
the mass of hydrogen is 1 and oxygen is 16.
1 molecule of water=18/6.022×10^23
=2.99×10^-23
is it match with your answer
say?
yes
ok then
the approx value is 3 × 10^-23
thank u
i have forget it
ur welcome
thanks for selecting as brainliest
