Suppose three mass measurements are taken as follows: 210 ± 15 kg, 28 ± 5 kg, and 33 ± 6 kg. find the sum of the masses, mm.
on a separate piece of paper, write the equation for the sum of masses: m = m1 + m2 + m3. find the value of m, δm, and mm. show your work. note: refer to figure 10 to determine the appropriate equation for calculating δm.
write your name and date on the paper. take a clear photograph of your work and upload the image into photo 3.
record the value of mm in data table 1.

Asheet of steel 1.5 mm thick has nitrogen atmospheres on both sides at 1200oc and is permitted to achieve a steady-state diffusion condition. the diffusion coefficient for nitrogen in steel at this temperature is 6 x 10- 11 m2 /s, and the diffusion flux is found to be 1.2 x 10-7 kg/m2 -s. also, it is known that the concentration of nitrogen in the steel at the high-pressure surface is 4 kg/m3 . how far into the sheet from this high-pressure side will the concentration be 2.0 kg/m3 ? assume a linear concentration profile.
