288 K or 15 C
305 k
For the pressure to remain the same, the temperature would double if the volume also doubled.
A sample of gas occupies 1.55L at STP. What will the volume be if the pressure is increased to 50 atm while the temperature remains constant?
.004g/cm^3
The volume of graphite is dependent on its mass and density. You can calculate it only if you know the sample's mass and density. The same goes for any other substance or object.
Volume of a sample = (its mass) divided by (its density)
You calculate the volume of three-dimensional figures, not of numbers like pi.
The core sample is a cylinder. The volume of any cylinder is (pi) x (radius)2 x (length).
Density of a substance = (mass of a sample of the substance) divided by (volume of the same sample)
You cannot. If you know the volume, temperature and pressure of a pencil, you will be no closer to knowing its mass!
density= mass/volume 30g/7500cm3=.004g/cm3
This depends on the nature and form of the sample:- for a solid with a regulate shape weight the sample and calculate the volume from the dimensions; density is the ratio between mass and volume. You can measure the volume of great sample by water displacement.- for other solids use a pycnometer- for liquids use a densimeter (simple or electronic)etc.

A sample of gas occupies 1.55L at STP. What will the volume be if the pressure is increased to 50 atm while the temperature remains constant?
Increases in direct proportion to the increase in temperature (on an absolute scale).
The volume ofhydrogen is 64,84 L.
