Question

what are number of moles present in 12 gram of hydrogen atom​

Answer 1

6 moles are present in 12 gram of hydrogen atom.

Step by step explanation:

• Given data,

Mass of Hydrogen atom(W) = 12 g

and the Molar mass of Hydrogen atom(M.M) = 2 g/moles

• Formula used,

No. of moles (N) = $\frac{W}{M.M}$

• Calculation of N of Hydrogen atom,

W = 12g and M.M = 2g/moles

N = $\frac{12}{2}$ = 6 moles

Number of moles present in 12g Hydrogen atom are 6 moles.
