The molar mass of vanadinite is 1416.27 g/mol. Looking at
the molecular formula we can see that there is 1 mole of Cl for every mole of
vanadinite. Therefore:
mass percent = [(1 mole Cl * 35.45 g/mol) / (1 mole
Pb5(VO4)3Cl * 1416.27 g/mol)] * 100%
<span>mass percent = 2.50%</span>
Answer:
The correct answer is d. 6H20 + 6CO2.
The reactant in the chemical reaction 6H2O + 6CO2 ---> C6H12O6 + 6O2 is 6H20 + 6CO2. Remember that the reactant is always at the left side of the equation. So the correct answer is 6H20 + 6CO2 since it's in the left of the equation. I hope this answer helped you.
