Final answer:
To calculate the mass of CaCl2, multiply the given mass percentage of the solution by the mass of the solution. Therefore the correct option is B)1.50g.
Step-by-step explanation:
To calculate the mass of CaCl2, multiply the given mass percentage of the solution by the mass of the solution. The mass percentage of the solution is 10.00%, so you can calculate the mass using the equation:
Mass of CaCl2 = (10.00% / 100) * 15.00 g = 1.50 g
Therefore, the correct answer is option B) 1.50 g.
