<h3>
Answer: 144 g</h3>
Explanation:
Mass of glucose = moles × molar mass
∴ Mass of glucose = 0.8 mol × 180 g mol⁻¹
= 144 g
∴ the mass of glucose you need to have 0.8 mol of glucose = 144 g
Initial volume of the balloon = = 348 mL
Initial temperature of the balloon =
Final volume of the balloon = 322 mL
Final temperature of the balloon =
According to Charles law, volume of an ideal gas is directly proportional to the temperature at constant pressure.
On plugging in the values,
Therefore, the temperature of the freezer is 276 K
Molality is the moles of solute per kg of solvent.
Moles of NH₄Cl = 2.4 / (14 + 4 x 1 + 35.5)
= 0.0448 mole
Molality = 0.0448 / (19.4 / 1000)
= 2.31 m
Answer:
Condensation occurs when a gas changes into a liquid.
Explanation:
Condensation is when a gas becomes a liquid. It happens when a gas, like water vapor, cools down. Matter can exist in three different states: solid, liquid or gas.
