Hope this helps! ;)
Solids, liquids, and gases can all dissolve.
Dissolving depends on the molecules of the substance doing thedissolving, called the solvent, and the molecules of the substance being dissolved, called the solute.
Dissolving is the process in which these molecules interact and attract each other to form a solution.
Answer:
Average atomic mass = 55.83 amu
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
For first isotope, Fe-54:
% = 6 %
Mass = 53.94 amu
For second isotope, Fe-56:
% = 92 %
Mass = 55.93 amu
For third isotope, Fe-57:
% = 2 %
Mass = 56.94 amu
Thus,
<u>Average atomic mass = 55.83 amu</u>
Calculate formula and then substitute values into the formula for mass.
V = lwh
= (3.12)(527)(220)
= 361732.8
M = Dv
= (721)(361731.8)
≈ 2608086.28 kg
I'm not exactly sure so :/
