Final answer:
The number of grams of AlCl3 in the given solution is 18750 grams.
Step-by-step explanation:
To find the number of grams of AlCl3 in the given solution, we can use the formula:
Grams of AlCl3 = Volume of solution (in mL) × Molarity × Molar mass of AlCl3
Plugging in the values, we get:
Grams of AlCl3 = 7.50 x 10^2 mL × 2.5 M × 133.33 g/mol = 18750 g
Therefore, there are 18750 grams of AlCl3 in the given solution.
