Answer:
28g
Solution. Hence, 2 moles of nitrogen atoms weigh 28g.
Because the sublevels 1s only has one shape ,and it only contains 2 elections...
Answer:
3.50 molal
Explanation:
Molality → Moles of solute / kg of solvent.
Let's convert the solvent's mass from g to kg
16.2 g . 1kg / 1000 g = 0.0162 kg
Let's determine the moles from the solute
2.61 g . 1 mol / 46 g = 0.0567 moles
Molality → 0.0567 mol / 0.0162 kg = 3.50 m
Latent heat, also called the heat of vaporization, is the amount of energy necessary to change a liquid to a vapour at constant temperature and pressure. The energy required to melt a solid to a liquid is called the heat of fusion
POH = - log [ OH-]
pOH = - log [ 1 x 10⁻¹²]
pOH = 12
