Litharge, PbO, is an ore that can be roasted (heated) in the presence of carbon monoxide, CO, to produce elemental lead. The reaction that takes place during this roasting process is represented by the balanced equation below.
PbO(s) + CO(g) ! Pb(`) + CO2(g)
Calculate the percent composition by mass
of oxygen in litharge (gram-formula mass = 223.2 grams per mole). Your response must include both a numerical setup and the calculated

ans is no, the data set cannot be plotted as a single circle graph

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
