Answer:
2.35 M
Explanation:
Molarity is mol/L of solution. We have to convert the g to mol and the mL to L. G to mol uses the molar mass of the compound. The molar mass of NaNO₃ is 85.00g/mol.
[tex]50.0gNaNO3*\frac{1molNaNO3}{85.00gNaNO3} = 0.588molNaNO3[/tex]
Then you have to convert mL to L.
[tex]250mL*\frac{1L}{1000mL} = 0.250L[/tex]
Now divide the mol by the L.
[tex]\frac{0.588mol NaNO3}{0.250L} = 2.352 M[/tex]
Round to the smallest number of significant figures = 2.35M
