I think it’s d not 100% sure tho
Answer:
Molarity.
Explanation:
- The molarity (M) of a solution is defined as the no. of moles of solute that dissolved in 1.0 liter of the solution.
M = (mass / molar mass) of the solute (1000 / volume of the solution).
<em>So, the best measurement of concentration for describing the concentration of a solid solute dissolved in one liter of a liquid solution is Molarity.</em>
I think it's RbCl and CaO
Answer:
Explanation:
According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,
or,
where,
= initial volume of gas
= final volume of gas
= initial moles of gas
= final moles of gas
