Answer:
Es la capacidad, el poder de un átomo en una molécula para atraer a los electrones hacia sí.
Explanation:
Explanation:
Since pressure remained constant, we can eliminate P from the equation
Doing some algebra and converting temperature to Kevin by adding 273, you should obtain the same result.
Answer:
Molality is 0.25 m
Explanation:
Molality → Moles of solute / kg of solvent
We need the moles of solute → 0.124 moles
22.4 g . 1 mol / 180 g = 0.124 moles
We need the mass of solvent in kg. We determine the mass of solvent with density.
Density = Mass / Volume
Mass = Density . volume → 1 g/mL . 500 mL = 500 g
If we convert the mass in g to kg → 500 g . 1kg / 1000 g = 0.5 kg
In conclussion, molality → 0.124 mol / 0.5 kg = 0.25 m
Answer:
11 g
Explanation:
1 mole of carbon dioxide =44 g
therefore for 0.25 mole = x
x = 44 × 0.25
x = 11.00g
