Biuret reagent. This is the answer
<u>Answer:</u> 1.461 g of NaCl is dissolved in the solution.
<u>Explanation:</u>
Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L.
The formula used to calculate molarity:
.....(1)
Given values:
Molarity of solution = 0.050 M
Molar mass of NaCl = 58.44 g/mol
Volume of solution = 500.0 mL
Putting values in equation 1, we get:
Hence, 1.461 g of NaCl is dissolved in the solution.
