2H2+O2→2H2O
We have to be aware that the number of atoms are the same on both reactant side and product side.
Option b I think :) hope this helped!
Answer : The mass of NaCl required are 14.61 grams
Explanation : Given,
Molar mass of NaCl = 58.44 g/mole
Volume of solution = 500.00 mL
Molarity of NaCl = 0.5 M = 0.5 mole/L
Molarity : It is defined as the number of moles of solute present in 1 liter of solution.
Formula used :
Now put all the given values in this formula, we get:
Therefore, the mass of NaCl required are 14.61 grams
