Explanation:
Hello!
In this case, for the undergoing chemical reaction:
We evaluate the yielded moles of zinc hydroxide by each reactant as shown below:
In such a way, since the water yields a smaller amount of zinc hydroxide we conclude it is the limiting reactant so the maximum mass is computed below:
Because the water limits the yielded amount of zinc hydroxide.
Best regards!
Answer : The correct option is, 0.21 moles
Solution : Given,
Molarity of the solution = 0.85 M = 0.85 mole/L
Volume of solution = 250 ml = 0.25 L
Molarity : It is defined as the number of moles of solute present in one liter of the solution.
Formula used :
Now put all the given values in this formula, we get the moles of solute of the solution.
Therefore, the moles of solute is, 0.21 moles
