You witnessed a student throw away a broken beaker in the regular trash can. Which of the following is the most important reason to alert your instructor?

Calculate the molarity of 48.0 ml of 6.00 m h2so4 diluted to 0.250 l .

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.

Witch two conditions can limit the usefulness of the kinetic molecular theory in describing gas behavior?
