You need to make a stock solution of a known copper concentration for your experiment. you start by weighing out a piece of pure copper wire which has a mass of 0.211 g. you then add 1.0 ml of 12 m hno3, 3.0 ml of h2o and 2.0 ml of 12 m nh4oh to dissolve the copper metal.
the moles of copper that are in the solution = 0.00332 mols. now i need to find the final molarity of copper in the solution.

What happened in 2012 and how does it illustrate the importance of understanding the sun and how it works?

Imagine that twenty i. u.’s of enzyme z were catalyzing the above reaction for one minute, under vmaxconditions, in a 3.00 ml assay volume. the assay is buffered with 20 mm phosphate buffer, ph 7.60. what will the ph be at the end of that one minute?

Amines are good nucleophiles, even though they are neutral molecules. how would the rate of an sn2 reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? amines are good nucleophiles, even though they are neutral molecules. how would the rate of an reaction between an amine and an alkyl halide be affected if the polarity of the solvent is increased? because both reactants in the rate-limiting step are neutral, the reaction will be faster if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will be slower if the polarity of the solvent is increased. because both reactants in the rate-limiting step are neutral, the reaction will occur at the same rate if the polarity of the solvent is increased. request answer
