molarity of FeCl3 is .40 g/mol
we
had 5.0 mL of FeCl3 (0.40g/mL) which equals 0.08g divided by 162.2g
FeCl3 which equals 0.000493 moles or 4.9 x 10^-4

Calculating Concentration Calculate the molarity of B-carotene if 9.00 x 103 ug of B-carotene (536.87 g/mol) is dissolved to form 20.00 mL of solution. Remember that molarity has units of (moles of solvent)/(Liter of solution). 2. Use correct Sig Figs and include units. 3. When we eat carrots or other fruits and vegetables that contain carotenes, only 17-459 of the carotenes are absorbed by our bodies. If you consumed 1325 ug of B-carotene, what is the mass range that could...
