Answer:
Explanation:
The pressure, the volume and the temperature of an ideal gas are related to each other by the equation of state:
where
p is the pressure of the gas
V is the volume of the gas
n is the number of moles
R is the gas constant
T is the absolute temperature
For the gas in this problem:
n = 2.00 mol is the number of moles
V = 17.4 L is the gas volume
p = 3.00 atm is the gas pressure
is the absolute temperature
Solving for R, we find the gas constant:
D. there is one atom of sulfur and three atoms of oxygen
We can see here that the both measurements are accurate. This is the true because the both values are in the correct number of significant figures.
<h3>What is density?</h3>
The term density has to do with the ratio of the mass to the density of the object. We know that the accuracy of a measurement has a lot to do with the number of significant figures in the measurement. In this case, we are told that two students in a lab are asked to calculate the density of a block with a mass of 31.0 g; they are not told how many digits to round their measurements. Student A finds length to be 2 cm width to be 4 cm and height 8 cm. Student B finds the length to be 2.65 cm, width to be 4.20 cm, and height to be 8.35 cm.
For the first student, the density is obtained as;
Density = mass/ volume
= 31.0 g/ 2 cm * 4 cm * 8 cm
= 0.5 g/cm^3
For the second student;
Density = mass/ volume
= 31.0 g/2.65 cm * 4.20 cm * 8.35 cm
= 0.33 g/cm^3

Gases, bc its expand the most upon heating because the intermolecular space is more than in solids or liquids.
intermolecular space = the space between each particles
