What is the best summary of avogadros law?
Equal amounts of all gases have the same volume at the same conditions.
What is the equation to measure lung volume?
No equation is possible, lung volume is measured by a machine in to which you breath.
If 20.00mL of a 1.50M solution of KBr is diluted to a final volume of 150.0mL what is the new molar concentration?
initial molarity*initial volume= final molarity*final volume Initial molarity= 1.50M Initial volume= 20.00ml Final Volume=150.0ml Thus final molarity =1.50M*20ml/150ml=0.200M. New molar concentration= final molarity
Which equation correctly expresses the calculation of density?
Density is calculated by dividing the mass of an object by its volume. Mathematically, the equation for density is density = mass/volume.
How do you get final volume of water?

What does avogadros law describe?
the relationship between volume and moles-APEX
What is the best summary of avogadros law?
Equal amounts of all gases have the same volume at the same conditions.
What evidence supports avogadros hypothesis?
PV/NrT, pressure(volume)/amount(constant)(temperature). When your temperature, volume, and pressure are all the same, you get the same number of particles. This is avogadros hypothesis. Let's say that you have to balloons. They have the same temperature, volume, and pressure. If you weigh the gases in the balloon, you will find that there is the same amount of particles. In fact Dalton did this was able to find out the amount of particles (atoms) by the mass of objects.
How can you convert the formula for density to find the volume of an unknown object?
The formula for finding density is: Density= Mass/Volume or d= m/v. if you multiply both sides of the equation by the Volume: vd= v m/ v , volume cancels on the right and you get the equation: Density x Volume= Mass or dv=m. by dividing both sides by the Density: d v/ d =m/d, density will cancel on the left and our final equation is Volume=Mass/Density or v=m/d
How much fog can 4 ounces of water produce?
Firstly, 4 ounces is equal to 120ml, which equals 120g. Using the gas volume equation V = nRT/p, and by filling in the correct numbers, the volume of fog comes out as 4.8m cubed. The amount of gas can then be determined using A = Vn (Amount, volume & no of particles [120*avogadros no.]) So, A = 1400fg. fg => foglets, the standard unit for measuring amount of fog.
What is the volume equation for a trapazoid?
Volume = 0.
What is the equation to measure lung volume?
No equation is possible, lung volume is measured by a machine in to which you breath.
What does equation V1 c1 v2 c2 stand for where c concentration and v is for volume?
v1= initial volume c1= initial concentration v2= final volume c2= final concentration For example, you have 10mL of an unknown substance with a concentration of 0,5mol/L. If you add 50mL, what will the final concentration be. V1= 10mL C1= 0,5mol/L V2= 60mL C2= x 10/0,5=60/x You must start by putting everything in the same mesure. We'll use mL here. So 0,5-->1000mL= 50-->10mL 50x60= 300 300/10= 30 30 is your C2
What happens to the volume of air when it is heated?
The volume of air increases proportionally as it is heated, according to the formula: PV/T = P'V'/T' Where P, V, and T are initial values for pressure, volume and temperature in absolute terms and P',V',and T' are the final values with a constant pressure the equation becomes: V/T = V'/T' to solve for final volume the equation is: VT'/T = V' if V=1cu. meter, T = 200K and T' = 300K then 1 cu.meter x 300K/200K = 1.5 cu.meter
How do you find the radius of a cone if you have height and volume?
Use the equation for the volume of a cone, replace the known height and volume, and solve the resulting equation for the radius.
If 20.00mL of a 1.50M solution of KBr is diluted to a final volume of 150.0mL what is the new molar concentration?
initial molarity*initial volume= final molarity*final volume Initial molarity= 1.50M Initial volume= 20.00ml Final Volume=150.0ml Thus final molarity =1.50M*20ml/150ml=0.200M. New molar concentration= final molarity
When would you use water displacement?
Usually water displacement is used to determine the volume of an object. When the object is added to the water, the amount of displacement can be measured. I don't know if there is an equation to do this, but it most likely involves subtracting the final volume from the initial volume.~Jeff Johnsonwww.jeffjohnsonis.com
