If a beaker has 9.32 x 1039 atoms of neon gas, which statement below would correctly describe how to convert to moles of neon? 1.Start with Avogadro’s number and multiply it by 9.32 x 10^39 atoms.
2.Start with Avogadro’s number and divide it by 9.32 x 10^39 atoms.
3.Take 9.32 x 10^39 atoms and divide by Avogadro’s number.

There are 6.022, 104 atoms of hg in 1 mole of hg the number of atoms in 45 moles of hg can be found by multiplying 4.5 by 6.022, 102 which is the number of atoms in 4.5 moles of hg, correctly written in scientific notation with the correct number of significant figures? 0 21,109 0 21,100 271, 1024 27.099, 100 mark this and retum save and exit submit

Consider the reaction: n2(g) + o2(g) ⇄ 2no(g) kc = 0.10 at 2000oc starting with initial concentrations of 0.040 mol/l of n2 and 0.040 mol/l of o2, calculate the equilibrium concentration of no in mol/l how would this be done?
