In a common medical laboratory determination of the concentration of chloride ion in blood serum, a serum sample is titrated with a hg(no3)2 solution
2cl- + hg(no3)2 ? 2no3- + hgcl2
what is the cl concentration in a 0.25-ml sample of normal serum that requires 1.46 ml of 5.25 x 10-4 m hg(no3)2 to reach the endpoint?

How many moles of n2 you have in 476 l sample at stp?

Starch and are common polysaccharide carbohydrates found in plants. sucrose glycogen fructose cellulose

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here.
