Help me cacualte the [FeSCN2+]std​?

Calculate the [FeSCN2+]std. Recall that a high initial concentration of Fe3+ ions forces the reaction far to the right, using up nearly 100% of the initial SCN– ions. Using stoichiometry and the balanced equation, it is assumed that for every mole of FeSCN2+ produced, one mole of SCN– is used up. So it is assumed that [FeSCN2+]std, is equal to the [SCN–]i. Using C1•V1=C2•V2, calculate the initial concentration of SCN– from step 3 based on its dilution with Fe(NO3)3.

q 1 )Find a vector in the direction of ⟨−5,3⟩⟨-5,3⟩ with magnitude 41

q 2)Find a vector in the direction of ⟨3,5⟩⟨3,5⟩ with magnitude 20

Give your answer as a vector: ⟨number,number⟩⟨number,number⟩.
