The atomic mass of rubidium listed in the periodic table to determine the mass of Rb−87 is 86.13 amu.
<h3>What is atomic mass?</h3>
The atomic mass is the weight of the roton neutron and electron present inside the nucleus and shells of an atom and the elements are arranged on the basis of this only.
The mass of Rb−85 is 84.9118 amu for 1 amu it will be
amu = 84.9118 / 85 = 0.99
so, the amu for Rb−87 will be,
AMU = 87 × 0.99 = 86.13 amu.
Therefore, the mass of Rb−87 is 86.13 amu for atomic mass of rubidium listed in the periodic table.

N (H2O) = m/M
m (H2O) = 1.4 kg = 1400g
M (H2O) = 2 x 1 + 16 = 18g/mol
n (H2O) = 1400/18 = 77.8mol
