2AgNO3 + BaCl2 + 2AgCl + Ba(NO3)2
How many grams of AgCl, silver chloride, are produced from 9.3 g of AgNO3,
silver nitrate? Round your final answer to 2 places after the decimal.

Respuesta :

Answer: 7.88 g of AgCl are produced from 9.3 g of [tex]AgNO_3[/tex]

Explanation:

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} AgNO_3=\frac{9.3 g}{169.8g/mol}=0.055moles[/tex]  

[tex]2AgNO_3+BaCl_2\rightarrow 2AgCl+Ba(NO_3)_2[/tex]  

According to stoichiometry :

2 moles of [tex]AgNO_3[/tex] produce =  2 moles of [tex]AgCl[/tex]

Thus 0.055 moles of [tex]AgNO_3[/tex] will produce=[tex]\frac{2}{2}\times 0.055=0.055moles[/tex]  of [tex]AgCl[/tex]

Mass of [tex]AgCl=moles\times {\text {Molar mass}}=0.055moles\times 143.3g/mol=7.88g[/tex]

Thus 7.88 g of AgCl are produced from 9.3 g of [tex]AgNO_3[/tex]
