Answer: The change in volume will be 9.30 L
Explanation:
To calculate the new pressure, we use the equation given by Boyle's law. This law states that pressure is directly proportional to the volume of the gas at constant temperature.
The equation given by this law is:
where,
are initial pressure and volume.
are final pressure and volume.
We are given:
Putting values in above equation, we get:
The change in volume will be (44.3-35.0)L = 9.30 L
Answer:
rises to an altitude where the pressure is 27.5 and the temperature is 10°C, its volume there is.

Answer:
Option C
Explanation:
No. of Molecules=(Given Weight/Molar weight)*Avagadro No.
Given weight of H2O=3.01g
Molar weight of H2O=18g
On applying the formula, we get:
No. of Molecules=(3.01/18)*6.023*10²³=1.01*10²³
The correct answer is an ionic bond
Answer:
0.45M
Explanation:
The following were obtained from the question:
C1 = 0.75M
V1 = 100mL
V2 = 165mL
C2 =?
Applying the dilution formula C1V1 = C2V2, the concentration of the diluted solution can be calculated for as follows:
0.75 x 100 = C2 x 165
Divide both side by 165
C2 = (0.75 x 100) /165
C2 = 0.45M
The concentration of the diluted solution is 0.45M
