Question

the number of moles
()12.044 x 1023 molecules of water (atomic mass of H=1u, 0 = 16u)
​

Answer 1

Answer:

I assume you are required to find number of moles of 12.044 x 10^23 molecules of water.For this we will use well-known formula :

N(number of molecules)=n(number of moles) x NA(constant), the result is therefore equal to

n=N/NA = 12.044* 10^23 molecules/ 6.02 * 10^23 molecules/mol = 2mol

I hope this made it clear for you
