inysia [295]

Answer:

4.17 g/mL

Explanation:

In order to determine the density of the solid, we need to know both its mass and its volume.

The mass is already given to us by the problem, 45.0 g.

As for the volume, we can determine it by using Archimedes' principle. It states that the volume of water displaced by an object when submerged is equal to the object's volume.

Water displaced = 75.8 mL - 65 mL = 10.8 mL

Finally we calculate the density of the solid:

Density = mass / volume = 45.0 g / 10.8 mL

Density = 4.17 g/mL

A glass laboratory flask is filled with gas at 24 ∘C and 0.95 atm pressure, sealed, and then heated to 104 ∘C. What is the press

Elan Coil [88]

The pressure inside the flask on heating it is given as 1.21 atm.

Explanation:

As per Guy Lussac's law, the pressure of any concealed volume of gas particles will be directly proportional to the temperature of the container of the gas particles.

So P ∝ T

To convert celsius to kelvin, add 273.15 to the temperature value in celsius

Since, here the initial temperature of the flask is given as 24°C, so in kelvin it will be 297.15 K. Similarly, the final temperature is said to be 104°C which will be equal to 377.15 K. Then the final pressure will be increased as there is increase in temperature. So, the final pressure inside the flask can be obtained as

$\frac{P_{1} }{T_{1} } = \frac{P_{2} }{T_{2} }$

$P_{2} = \frac{P_{1} }{T_{1} } \times T_{2} =\frac{0.95}{297.15} \times 377.15 =1.21\ atm$

So, the pressure inside the flask on heating it is given as 1.21 atm.
