1 a.m.u.=1.6726219xx10^(-27) kg.

Explanation:

1 atomic mass unit (a.m.u.) is the mass of a proton or a neutron which is equal to 1.6726219xx10^(-27) kg.

The mass of a Hydrogen atom is 1 a.m.u. But, also we can say that the molar mass of a hydrogen is equal to 1g/"mol" and this is because:

1.6726219xx10^(-24) gxx6.022xx10^(23)=1.007"g/mol"

which is close to the mass that you find in a periodic table.
