2. A container has a mass of 70g when it is empty. The same container when filled with water has a total mass of 210g and when filled with syrup has a total mass of 490g. Using the equation in question 1, to determine iii: i. The mass of the water=140 g ii. The mass of syrup= 420 g iii. The relative density of syrup = 3 iv. The density of syrup=3 g

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.
