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
= 2.659 g NaCl
