I keep on getting D... idk why... i give up someone please tell me how its done

here is the q 2021 hsc

This may sound a bit silly but how did they just know how to sub in these concentrations of Ag and CrO4. I am so confused. I tried subbing in another point.. didnt work

btw the answer is half of what i got

Here is the question: and here is my working

6 foot 8 (yes im a tall boi)

so do I find the number of moles of thiocyanate that reacted with the excess Ag and subtract from the total Ag used. Then do I make use of the fact that everything is 1:1 so no. of mol of salt = no. of mol Ag used and divide by volume and then multiply by 10 cuz its diluted? thats what i did in...

your working makes sense but the answer is 0.12 i still dont get how
