A0.03 mol sample of nh4no3(s) is placed in a 1 l evacuated flask, which is then sealed and heated. the nh4no3(s) decomposes completely according to the balanced equation above. the total pressure in the flask measured at 400 k is closest to which of the following? (the value of the gas constant, r, is 0.082 l atm mol-1 k-1.)

Particles vibrate in a rigid structure and do not move relative to their neighbors.

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.
