It is homogeneous mixture of two non reactive substance.
Molarity is defined as the number of moles of solute per 1 L of solvent.
the mass of NaCl in the solution is 87.75 g
number of moles of NaCl is calculated by dividing mass present by molar mass
number of NaCl moles = 87.75 g / 58.44 g/mol = 1.502 mol
the number of NaCl moles in 500 mL is - 1.502 mol
therefore number of NaCl moles in 1000 mL is - 1.502 mol/ 500 mL x 1000 mL/L = 3.004 mol
molarity of NaCl is - 3.004 M
answer is D. 3.00 M
