Hi,

 

According to the USP <643> I need to prepare a solution of 0.75 mg/mL of 1,4-Benzoquinone USP Reference Standard in order to get 0.5 mg/L or carbon (500 ppb). Could anyone please explain how the calculation is done? How do I know that I have to weigh in 0.75 mg of Benzoquinone and dilute in 1L of Water in order to get 500 ppb of carbon content?

 

Thanks for your help! :)
