The percent by mass of hydrogen in NH3 is equal to 1) 17/1 x 100
2) 17/3 x 100
3) 1/17 x 100
4) 3/17 x 100

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.

Show how to convert the temperature 84.7° c to kelvin. include all steps and label the final answer.
