200.0g of C6H5OH is reacted with 200.0g O2 according to the following reaction:
C6H5OH + 7O2 → 6CO2 + 3H2O
Identify the limiting reactant.
Identify the excess reactant.
Determine the theoretical yield of CO2.
How much excess reactant is left over after the reaction is complete?
If 153.g of CO2 is collected, determine the percent yield of CO2.

Limiting-O2

Excess-C6H5OH

Percent Yield- 64.87%

Explanation:

Message me if you want me to explain.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

will have a gram-molecular weight of 352g.
