Jasmine has discovered a fascinating rectangular box in an underground cave. She's a bit nervous to open the box (there might be some not-so-nice things involved), but
she's gathered as much data about the box as possible: it's 1.2 cm long, 19.1 cm
wide, and 3.6 cm high, and it has a mass of 32.6 grams. What is the density of
Jasmine's mysterious box? Please answer to within 0.01 g/cm3.

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.

What is the energy in joules of a mole of photons associated with visible light of wavelength 486 nm?

Be sure to answer all parts. the following equilibrium constants were determined at 1123 k: c(s) + co2(g) ⇌ 2co(g) k'p = 1.30 × 1014 co(g) + cl2(g) ⇌ cocl2(g) k''p = 6.00 × 10−3 calculate the equilibrium constant at 1123 k for the reaction: c(s) + co2(g) + 2cl2(g) ⇌ 2cocl2(g) 4.68 × 10 9 (enter your answer in scientific notation.) write the equilibrium constant expression, kp:
