You have $10mL$ of a $0\mathrm{.}25M$ aqueous solution of protein tyrosine kinase, and you need to make $5mL$ of a $0\mathrm{.}005M$ solution of protein tyrosine kinase. Show your calculations for how you would go about making the new solution.

Another way to report concentration is a $\%($w$/$v$)$ solution. This refers to the weight in grams of the solute per the total volume $($mL$)$ of a solution $x100.$

You are faced with a procedure to make sodium benzoate. Your plan is to react some $0\mathrm{.}75M$ sodium methoxide $($in methanol$)$ with some $0\mathrm{.}25M$ benzoic acid $($in methanol$)$ and then allow the methanol to evaporate.

$5.$ If you want to make $0\mathrm{.}025$ moles of sodium benzoate, what is the weight in grams of that product that you would expect?

$6.$ If your goal is to make $0\mathrm{.}025$ moles of sodium benzoate, you need to use $0\mathrm{.}025$ moles of benzoic acid. What volume of your starting benzoic acid solution will you need? Report this in $mL$ and $L.$

Can you please answer all these three questions
