Answer:
0.0005mol/kg
Explanation:
Molality = mole of solute/mass of solvent (kg)
From the question, we obtained the following data:
Mole of solute = 0.05mole
Mass of solvent = 100kg
Molality = 0.05/100
Molality = 0.0005mol/kg
The molality of the solution is 0.0005mol/kg

Answer is: carbon.
<span>During gamma emission the nucleus emits radiation without
changing its composition, if for example have nucleus with six
protons and six neutrons (carbon atom) and after gamma decay there
is nucleus with six protons and six neutrons.
Gamma rays are the electromagnetic waves with
the shortest wavelengths (1 pm), highest frequencies (300 EHz) and
highest energy (1,24 MeV).</span>
When a man travels from earth to space, the mass of the person, defined as the amount energy a matter has remains constant. However, when he moves to space, gravity decreases until such time that there is no gravity that acts on the person. Weight thus changes or decreases until the point of state called weightlessness.
