1 mole of gas = 22.7 litre ( at STP)
22.7 Litre of gas = 1 mole
1 litre of gas =
2.27 litre of gas = mole

1 mole of an ideal gas occupies 22.4 liters at STP - so 2 moles occupies 44.8 liters.
0.0987 moles
Number of Moles = concentration * volume (in litres)

We need to know the diameter of the wire to calculate the volume and the mass. Number of atoms is: 2,58.1023.r2, where r is the radius of the wire.
ANY closed cylinder of 4.0 litre will contain the same number of molecules of ANY gas as the 4.0 liter closed cylinder containing O2 gas at the SAME temperature and pressure, since then the volume only depends on the number of molecules, not on the kind of molecules of the gasses concerned
When you look at a graduated cylinder anywhere above eye level with the surface of the liquid, it distorts the view and the number (tick mark) you identify as the volume will not be accurate.
Calculate the volume of a single cylinder and multiply it by the number of cylinders.
Calculate it by multiplying the value of Pi by twice the radius - then multiplying that number by the height... I'll leave YOU to do the maths !
A good place to measure is the diameter of the circular end. That gives you the area of the circular end, and the only other number you need in order to calculate the cylinder's volume is its straight length.
Calculate the volume of one sweet. Calculate the volume of the jar and then divide the volume of the jar by the volume of a sweet.
Number of Moles = concentration * volume (in litres)
Formula for calculating the volume of a cylinder = pi*radius2*length giving your answer in cubic units. Therefore: pi*42*9 = 452.3893421 cubic units. To the nearest whole number: 452 cubic units.
The formula to find the volume of a right cylinder is height times area of the circular base. This volume in cubic feet is then multiplied by 7.48 to find the number of gallons.

You can't. There are an infinite number of cylinders with different dimensionsthat all have the same volume, so the volume alone isn't enough informationto tell you the dimensions.
It could be any positive number of centimeters. The volume depends not only on the radius, but also on the height of the cylinder.
The volume of this cylinder is: 550 cubic units.
You cannot determine the height and diameter from just the volume because there is an almost infinite number of combinations of height and diameter that could create a particular volume.
