A woman is swimming across a cold lake. Her body temperature is 98 degrees and the lake water is 60 degrees. Which has more thermal energy, the woman or the lake? Explain your answer!

What is the number of moles in 15.0 g ash3?

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.
