Question

The mass of an atom of hydrogen is 1.0008u. what is the mass of 32 atoms of hydrogen

Answer 1

Answer:

32u

Explanation:

if one atom is of mass 1u then 32 actions of hydrogen gas has a mass of 32*1==32

Answer 2

Answer:

32.0256g will be the mass of 32 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 32 atoms we can get the mass by multiplying 1.008 to 32 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 = 32x 1.008

On solving we will get the value of mass of 32 atoms of hydrogen to be 32.0256g
