1. In the human body the toxic compound hydrogen cyanide is neutralized by the acid, H₂S₂O₃, according to the reaction: HCN + H2S2O3 --> HCNS + H2SO3.  If 1000.g of H₂S₂O₃ is available in the body, will this be enough to neutralize 2000.g of HCN swallowed by a person?

2000.g HCN*(1 mole HCN / 27.03g HCN)*(1 mole H₂S₂O₃ / 1 mole HCN)*(114.16g H₂S₂O₃ / 1 mole H₂S₂O₃) = 8447 g H₂S₂O₃, no it wouldn't be enough to neutralize 2000.g HCN

I'm not entirely sure if I did this correctly so I'd appreciate it if someone could check it for me, thank you in advance.

Anyone know how to do this?

You are doing fine.

Are you sure amounts listed in the question were 1000 g and 2000 g and not 1.000/2.000 g? Not that it will change the final answer.

Well originally they were 1.000mg and 2.000mg but i converted them before starting the problem so I posted the converted values, that's why I placed a decimal pt. at the end to preserve the number of significant figures.

Thank you.
