Question

77. What mass of silver nitrate will react with 5.85
of sodium chloride to produce 14.35 g of silver
chloride and of sodium nitrate, if the law of
conservation of mass is TRUE ?
(A) 7.15 g
(B) 17.00
(C) 3.3
(D) 4.88
explanation​

Answer 1

Hey mate!!
_______________★_★

AgNO3 + NaCL _____> AgCl + NaNo3

i.e,

1 mole AgNO3 reacts with 1 mole NaCL to produce 1 mole AgCl.

A/Q

mole of AgCl obtained =
molecular wt./given wt.

= 143.5/14.35 = 0.1mole

so,

to obtaine 0.1 mole AgCl , 0.1 mole AgNO3 required.

and, 0.1 mole AgNO3 = 170 × 0.1 = 17g

your answer is option (B)

hope it helps !!
