Aclosed system consists of 0.4 kmol of propane occupying a volume of 10 m3 . determine
(a) the weight of the system, in n, and
(b) the mass-based specific volume, in m3 /kmol and m3 /kg respectively. let g = 9.81 m/s2 .

In positive numbers less than 1, the zeros between the decimal point and a non-zero number are blank significant

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
