The answer is True! Hope this helps correct me if I’m wrong
To solve such this we must know the concept of chemical reaction and dehydration reaction. Therefore, dehydration means to remove water from a compound.
<h3>
What is chemical reaction? </h3>
Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
Dehydration is a chemical process in which removal of water molecules from a compound take place using suitable reagent. The best reagent for dehydration can be any reagent that is water loving.
Therefore, dehydration means to remove water.

Answer:
M = 0.23 M
Explanation:
Given data:
Molarity of solution = ?
Mass of NH₄Br = 4.50 g
Volume of solution = 213 mL (213 mL× 1L /1000 mL = 0.213 L)
Solution:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / L of solution
Number of moles of NH₄Br:
Number of moles = mass/molar mass
Number of moles = 4.50 g / 97.94 g/mol
Number of moles = 0.05 mol
Molarity:
M = 0.05 mol/ 0.213 L
M = 0.23 M
Compounds are represented by chemical formulas
