An excess of `AgNO_(3)` is added to 100 mL of a 0.01 M solution of dichlorotetraaquachromium (iii) chloride. The number of moles of AgCl precipitated would be

Options

A. 0.002
B. 0.003
C. 0.01
D. 0.01

Answer

D

Explanation

`[Cr(H_(2)O)_(4)Cl_(2)]Cl+AgNO_(3) to AgCl+[Cr(H_(2)O)_(4)Cl_(2)]NO_(3)`
Molarity`=(wt)/("mol. Mass")xx(1000)/(vol.)`
`(wt)/("mol mass")="molarity"xx(vol.)/(1000)=(0.01xx100)/(1000)`
=0.001
