What did people get for the mercury question? (1 Viewer)

[cartoonmaiz]

I got something like 0.17mg/L for the concentration from the graph. My final result after calculations was something like 0.23mg/kg which is smaller than 0.5mg/kg so it is safe to eat.

 

[crazy_paki123]

its 0.23 mg/kg but apart from that you're right

 

[cartoonmaiz]

how u get 0.23... u been trolled bro.

 

[gayforniall]

Yeah I got 0.23 mg/kg

 

[cookeemonstah]

0.228 ---> 0.23

u use the graph to get 0.17mg/L then convert to mg/kg

(since volume wass 0.025L and mass 0.018 or something)

 

[remoteman213]

I used 0.165 mg/L and got 0.22 mg/kg

Will I lose a mark?

 

[someth1ng]

I got 0.23mg/L

I had no idea what was going on.

Then I was like WELL (thinking logically)

It's per litre, so I'll covert it to 25mL.

And the fish was in grams, so I put it in kilograms.

Then I randomly multiplied two numbers and got 0.228mg/L and said It was safe so eat. So glad everyone here is saying that it is the answer!

Best guess I've done throughout my entire HSC.

 

[Kimyia]

Yay I got 0.228

 

[lance687876]

I got 9902 mg per kg
L multiplied the mg per litre by 1000 to get mg only.
Shit

 

[Ant2511]

I also got 0.23

 

[jeffwu95]

[Rawf]

Yep it was, that's what I put as final answer too
