Answer:
Explanation:
Given that,
Mass, m = 456 mg = 0.456 g
Volume, V = 62 L
Since, 1 L = 1000 cm³
62 L = 62000 cm³
Using formula, density = mass/volume
So,
So, the density of an object is
<u>Answer:</u> The volume of the gas when the pressure and temperature has changed is 0.811 L
<u>Explanation:</u>
To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.
The equation follows:
where,
are the initial pressure, volume and temperature of the gas
are the final pressure, volume and temperature of the gas
We are given:
Conversion factor used:
1 L = 1000 mL
1 atm = 760 mmHg
Putting values in above equation, we get:
Hence, the volume of the gas when the pressure and temperature has changed is 0.811 L
