Answer and Explanation:
In H2O molecules, due to formation of intermolecular hydrogen bonds, there is molecular association. Large amount of energy is required to break these intermolecular hydrogen bonds. Intermolecular hydrogen bonding is not possible in H2S. Hence, its boiling point is lower and is a gas.
The volume of a 200 g sample of gold is 9.76 cm³
<u><em> calculation</em></u>
volume = mass /density
mass = 200 g
volume = 20.5 g/Cm³
volume is therefore = 200g / 20.5 g/cm³ = 9.76 cm³
0.398=mol/4.57L. mol= 1.818. 1.818*3=5.456. 5.456/(4.57L)=1.19 M
