For the following reaction, 6.12 grams of phosphorus (P4) are mixed with excess chlorine gas . The reaction yields 21.5 grams of phosphorus trichloride . phosphorus (P4) ( s ) chlorine ( g ) phosphorus trichloride ( l ) What is the theoretical yield of phosphorus trichloride

27.1 gram

Explanation:

To calculate the moles :

The balanced chemical reaction is:

As is the excess reagent, is the limiting reagent as it limits the formation of product.

According to stoichiometry :

1 mole of  give = 4 moles of

Thus 0.0494 moles of give =  of

Mass of

Thus 27.1 g  is the theoretical yield of phosphorus trichloride

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

output?
