Answer is: you can calculate the number of moles of water in a hydrate if you know the empirical formula
of the anhydride.
First measure mass of hydrate, after you heat hydrate, put sample of the compound on scale and measure the mass loss. The
lost mass is water. Now calculate the number of moles
of water and if the ratio is same as empirical formula, all water is lost.
Percent by mass : 4.10⁺³%
<h3>Further explanation</h3>
The concentration of a solution can be expressed in units such as molarity, normality, mass percent, volume percent etc.
mass solute= mass of NaOH
mass of NaOH :
mass solution = 1000 g
% mass :
Answer:
Kinetic energy
Explanation:
The kinetic energy of a particle is directly proportional to the temperature of it. An increase in temperature increases the speed in which the molecules move, causing t[he particles to collide with the walls of their containers.

Explanation:
Answer:
The answer to your question is 175 gallons
Explanation:
Data
60% antifreeze solution volume = ? = x
25% antifreeze solution volume = 25%
Final concentration 50%
Process
0.6x + 0.25(70) = 0.5(70 + x)
Simplification
0.6x + 17.5 = 35 + 0.5x
0.6x - 0.5x = 35 - 17.5
0.1x = 17.5
x = 17.5/0.1
Result
x = 175 gallons
