1- One mole is = 6.02 x 10^23 of anything, So one mole of atoms is 6.02x10^23.
2- when the balloon contains 0.15 moles of Co2 gas so:
the no.of molecules of Co2 = 0.15 x 6.02x 10^23
= 9.0 x 10^22
<h3><u>Answer;</u></h3>
0.180 moles of HgO
<h3><u>Explanation;</u></h3>
The atomic weight of mercury is 200.5
The atomic weight of oxygen is 16.0
Therefore; the molecular weight (per mole) of mercury oxide is 216.5 g
Hence;
Number of moles = 39 g/(216.5 g/mole)
= 0.180 moles of HgO.
