Molar mass FeSO₄ =151.908 g/mol
Volume = 450 mL / 1000 = 0.45 L
1 mol ----------- 151.908 g
n mol ----------- 0.8 g
n = 0.8 * 1 / 151.908
n = 0.00526 moles
M = n / V
M = 0.00526 / 0.45
M = 0.01168 mol/L⁻¹
hope this helps!

Answer:
c) hydrogen bonding.
Explanation:
Like water molecules which are H2O, hydrogen disulfide also has a bent shape. However, unlike water, it cannot have hydrogen bonding. Why? Because hydrogen bonding only occurs with nitrogen, oxygen, and fluorine. I haven't heard of disulfide linkages. And yes, H2S has London dipersion forces. All polar molecules have LDFs. But greater than that, H2S has dipole-dipole forces. Event though it is a dipole-dipole bond, it is still highly electronegative.
