i combined 5 mL of 0.20 M Fe with 1 mL of 4.0x10^-4 M HSCN and 4 mL of 0.5 M HNO3
i am asked to find the molarity of FeSCN.
i am given this statement: "The concentration of Fe is so high relative to that of HSCN that we can assume that all SCN present is in the complexed form, FeSCN. In...
yes i did assume that. but then i realized that to find the moles of KHP (part 1 of my question), i would divide the mass of KHP (0.737 g) by the molar mass of KHP (204.22 g/mol). is this correct? and yes, that link is exactly what i did in the experiment.
i'm not sure what that means. I'm just going by my lab book. i just know that the experiment was to titrate NaOH into KHP, and as far as i know, this was not a trick question. the bottle i took the KHP from said "KHP" on it.
what i did:
1) i put 0.737 g of KHP in a flask
2) then added ~25 mL of distilled water
3) and then titrated 34.06 mL of NaOH into it to get its equilibrium point,
how would i find: 1. the moles of KHP, and 2. the molarity of NaOH? and would the molar mass have any significance?
1. the...
when attempting questions with springs involved, i get confused with the spring PE formula.
i know its a simple formula but i don't get the correct answers
i know hooke's law is E = -kx
but in class i was given the formula E = 1/2 kx^2
is there a different time to use each of these...
