Answer:
The MOLARITY of a solution is determined by the ratio of moles of solute, (the material being dissolved), compared to the liters of solution. the equation is M=molL
For this NaCl solution we have a Molarity of 0.75 in 50 mL of solution.
Therefore
M = 0.75 M
V = 50 mL or 0.050 L
moles = x
0.75M=xmol0.050L
0.050L(0.75M)=xmol
0.0375mol=x
Use the molar mass of NaCl to convert the moles to grams.
0.0375molNaClx58.44gNaCl1molNaCl=2.19gramsNaCl
