Chemistry: Concentration of Solutions

What is the concentration of the chemist's silver(I) perchlorate solution?

A- 4.47 M

B- 0.00447 M

C- 4.47 x 10^-3 M

D- 447 M

The concentration of the silver(I) perchlorate solution is:

A- 4.47 M

To calculate the concentration of the silver(I) perchlorate solution, you need to divide the moles of solute by the volume of the solution in liters. In this case, the chemist measured out 6.7 x 10^2 moles of silver(I) perchlorate and diluted it to a final volume of 150 mL. First, convert the volume to liters by dividing by 1000 (150 mL = 0.150 L). Then, divide the moles of silver(I) perchlorate (6.7 x 10^2 moles) by the volume in liters (0.150 L) to obtain the concentration, which is 4.47 x 10^3 M. Since the question asks for the concentration rounded to significant digits, the answer is 4.47 M. Therefore, option A, 4.47 M, is the correct answer.

Understanding how to calculate the concentration of a solution is essential in chemistry. It involves determining the amount of solute present in a given volume of solution, which is crucial for various chemical reactions and experiments.
