Calculate the number of moles of sodium chloride in 500cm of 3m sodium chloride solution

Answer 1

The number of moles of sodium chloride in 500 cm3 of a 3M sodium chloride solution is 1.5 moles.

To calculate this, first convert 500 cm3 to liters (500 cm3 = 0.5 L). Then, multiply the volume (0.5 L) by the concentration (3M) to get the number of moles (1.5 moles).
