4.9 An open, shallow reservoir of a viscous, nonvolatile liquid is located inside a petrochemical plant. We wish to evaluate the unsteady absorption of H2S by the liquid if this gas is released to the atmosphere. The scenario considered is the sudden increase of the concentration of H2S in the air over the surface of the reservoir from zero to 0.1 mol%. If this level of contamination is maintained for 30 days, a. What is the minimum concentration of H2S in the liquid of the reser- voir at the end of this period? b. What is the maximum concentration? Additional information: Mass transfer inside the reservoir occurs by diffusion only. The reservoir can be approximated to a slab 0.1 m deep with a surface 200 m × 200 m. Convective mass transfer in the air flowing over the reservoir can be considered fast. The diffusivity of H?S in the liquid at 298 K and 1 atm (reservoir conditions) is 2 x 10?? m²/s, and the partition coefficient is K = 0.4 (ratio between molar concentration of H?S in air and molar concen- tration in the liquid).

1. (16.67 pts) What would be the IEEE 754 single precision floating point representation of n = -76543210.9876543210 1234 \times 10^{18}? For explanation, I want you to document the steps your perform, in this order: (1) What is n in decimal fixed point form (ddd.ddddd); (2) What is n in binary fixed point form (bbb.bbbb), storing the first 25 bits following the binary point; (3) What is the normalized binary number, written in the form $1.bbbbb...bbb \times 2^e$, storing 25 bits follow- ing the binary point? (4) What are the 23 mantissa bits, after the bits in bit positions -24, -25, ... are eliminated using the round to nearest, ties to even mode; exclude the 1. part which is not stored; (5) What is the biased exponent in decimal and in binary? (6) Write the 32-bits of the number in the order: s e m; and (7) Write the final answer as an 8- hexdigit number.
