Answer:
Step-by-step explanation:
To determine the mass of NaCl in 1.25L of 0.1035M solution, we can use the formula:
mass = concentration x volume x molar mass
where concentration is in molarity (M), volume is in liters (L), and molar mass is in grams per mole (g/mol).
The molar mass of NaCl is 58.44 g/mol.
Plugging in the given values, we get:
mass = (0.1035 M) x (1.25 L) x (58.44 g/mol)
mass = 7.3188 g
So, there is approximately 7.3188 grams of NaCl in 1.25L of 0.1035M solution.
