We wish to determine how many grams of [tex]$KNO_3$[/tex] can form when 100 mL of [tex]$0.40 \, \text{M} \, K_2CrO_4$[/tex] solution is added to excess [tex][tex]$AgNO_3$[/tex][/tex].
The balanced chemical equation is:
[tex]
2 \, AgNO_3(aq) + K_2CrO_4(aq) \rightarrow Ag_2CrO_4(s) + 2 \, KNO_3(aq)
[/tex]
How many moles of [tex]$K_2CrO_4$[/tex] are present in 100 mL of [tex]$0.40 \, \text{M} \, K_2CrO_4$[/tex]?
[tex]\text{Enter answer in moles of } K_2CrO_4.[/tex]
