Answer:
6.6 x 10⁻⁵ mol/L
Explanation:
First, we have to convert the moles from μmol to mol:
moles of solute= 33.0 μmol x (1 x 10⁶ mol)/1 μmol = 3.3 x 10⁻⁵ mol
Then, we convert the volume from mL to L:
volume = 500.0 mL x 1 L/1000 mL = 0.5 L
Finally, we calculate the concentration of the solution in mol/L by dividing the moles into the volume in liters, as follows:
mol/L = moles of solute/volume = 3.3 x 10⁻⁵ mol/(0.5 L) = 6.6 x 10⁻⁵ mol/L
Answer: 20.775 g S
Explanation: 3.9x10^23 atoms = 0.648 mol
Atomic mass S = 32.08
S in grams = 20.775
