Answer:
0.04751mol/L
Explanation:
So if molarity is mol/L, and we have 0.875L of solution, the only thing missing is the number of mole of solution.
We know that mole = mass/molar mass,
we know that mass = 3.08g and molar mass can be calculated by periodic table so 74.093 g/mol.
Now moles = 3.08g/74.093 g/mol = 0.041569mol
Now we can divide each other to find the molarity
0.041569mol/0.875 = 0.04751mol/L
