m) The mass of an atom of hydrogen is 1.008 u. What is the mass of 18 atoms of
hydrogen​

Answer 1

Answer:

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. On solving we will get the value of mass of 18 atoms of hydrogen to be
