Question

Calculate the mass for CaCl2 if the percentage by mass of the solution is 10.00 %. Given mass of the solution is 15.00 g. (Relative Atomic Mass: Ca = 40.1; CI = 35.5] A) 0.67 g B) 1.50 g C) 150.009 D) 10.00 g​

Answer 1

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.
