Question

How many moles of each product form when the given amount of each reactant completely reacts. C3H8(g)+5O2yields 3CO2(g)+4H2O(g). 4.6 moles of C3H8

Answer 1

Answer:  13.8 moles of $CO_2$ and 18.4 moles of $H_2O$ will be produced

Explanation:

The given balanced reaction is;

$C_3H_8(g)+5O_2(g)\rightarrow 3CO_2(g)+4H_2O(g)$

Given : 4.6 moles of $C_3H_8$

According to stoichiometry :

1 mole of $C_3H_8$ give = 3 moles of $CO_2$

Thus 4.6 moles of  $C_3H_8$ will give =$\frac{3}{1}\times 4.6=13.8moles$  of $CO_2$

1 mole of $C_3H_8$  give =  4 moles of $H_2O$

Thus 4.6 moles of $C_3H_8$ give =$\frac{4}{1}\times 4.6=18.4moles$  of $H_2O$

Thus 13.8 moles of $CO_2$ and 18.4 moles of $H_2O$ will be produced from the given moles of reactant $C_3H_8$
