Answer:
18.144g will be the mass of 18 atoms.
Explanation:
Since we know from the question that the mass of a single hydrogen atom is given as 1.008 u hence for calculating the mass of those 18 atoms we can get the mass by multiplying 1.008 to 18 which will give us the required result.
Since, we know that mass of one hydrogen atom = 1.008
So, the mass of 18 hydrogen atoms will be = 18x 1.008
On solving we will get the value of mass of 18 atoms of hydrogen to be 18.14.
