I guess it is called an Equation !!
The answer is circuit I believe.
The balanced chemical equation between calcium carbonate and hydrochloric acid:
Moles of =
Moles of HCl=
The mole ratio of
But we have per 0.03125 mol HCl
Hence, HCl is the limiting reactant. The amount of product formed would depend on moles of HCl.
Mass of =0.03125mol HCl *
Answer:
= 2.659 g NaCl
Explanation:
Molarity of a substance is given by the formula;
Molarity = moles/Volume in liters
Thus;
Number of moles = Molarity × volume in liters
= 1.3 M × 0.035 L
= 0.0455 Moles
But, the molar mass of NaCl is 58.44 g/mol
The mass of NaCl is therefore;
= 0.0455 g × 58.44 g/mol
<u>= 2.659 g NaCl</u>
