5 sty 2010 · The formula can be used to calculate the number of moles of gases from a given volume or vice versa; Simply cover the one you want and the triangle tells you what to do
25 sie 2015 · To find how much of air is occupied by molecules, we can multiply the number of molecules per unit volume by the volume of a molecule: $$n \times V = 2.5\times 10^{25} \text{ m}^{-3} \times 4\times 10^{-29} \text{ m}^3 = 0.001 = 0.1\%$$
28 maj 2024 · Calculate the volume of the balloon at -12.8 degrees Celsius, if the pressure and amount of gas in the balloon are held constant. In order to select the Gas Law that should be applied to solve this problem, each numerical quantity that is given in the problem must be assigned to a variable.
19 cze 2024 · You can calculate the buoyant force with the following buoyancy formula: B = ρ × V × g. where: ρ — Density of the liquid the object is immersed in, measured in kg/m³; V — Volume of the displaced liquid, measured in m³; g — Gravitational acceleration in m/s²; and; B — Buoyant force.
The short answer is that we need to use the volume of the fluid displaced V f l u i d in the formula because the displaced fluid is the factor that determines the buoyant force. What's the longer answer?
The ideal gas law can be used to calculate the volume of gaseous products or reactants as needed. In the laboratory, gases produced in a reaction are often collected by the displacement of water from filled vessels; the amount of gas can then be calculated from the volume of water displaced and the atmospheric pressure.
The ideal gas law can be used to describe a change in state for an ideal gas. In this video, we'll apply the ideal gas law to the initial and final states of a gas to see how changes in temperature and pressure affect the volume of the gas. Created by Sal Khan. Questions. Tips & Thanks.
