I came across this question in BOS multiple choice. Precisely its B isn't it? or is it not to scale?

 

[lolokay]

that graph shows the amount of carbon-14 remaining (note: the question asks for the amount of nitrogen-14)

the carbon-14 decays into nitrogen 14, so the amount of nitrogen 14 is 100 - [amount of carbon-14]

reading from the graph, we have 37g of carbon-14, so 100-37=63g of nitrogen-14

 

[ninetypercent]

i think it's C, because it's the amount of nitrogen -14 produced NOT the amount of carbon 14 remaining

ah thanks
I need to read the question carefully next time
