Using the Ideal Gas Law, you would find the volume of 1 mole of a gas at Standard Temperature and Pressure (STP). STP = 1 atm of pressure and 273 K for temperature P = 1 atm
It depends on the substance whose volume you know. > If you have a pure liquid or a solid, you use its density to calculate its mass and then divide the mass by the molar mass. If you have a solution, you multiply the molarity by the volume in litres. MOLES FROM VOLUME OF PURE LIQUID OR SOLID There are two steps: Multiply the volume by the density to get the mass. Divide the mass by the molar ...
The molar volume of a gas is derived from the ideal gas law #PV = nRT#: #PV = nRT -> V = (nRT)/P -> V/n = (RT)/P# Let's say you were given a temperature of 355 K and a pressure of 2.5 atm, and asked to determine the gas' molar volume at these conditions. Since molar volume refers to the volume occupied by 1 mole, you'd get
How do you find the volume of the solid with base region bounded by the curve #9x^2+4y^2=36# if cross sections perpendicular to the #x#-axis are isosceles right triangles with hypotenuse on the base? How do you find the volume of the solid with base region bounded by the triangle with vertices #(0,0)#, #(1,0)#, and #(0,1)# if cross sections ...
If the radius of its circular cross section is r, and the radius of the circle traced by the center of the cross sections is R, then the volume of the torus is V=2pi^2r^2R. Let's say the torus is obtained by rotating the circular region x^2+(y-R)^2=r^2 about the x-axis. Notice that this circular region is the region between the curves: y=sqrt{r^2-x^2}+R and y=-sqrt{r^2-x^2}+R. By Washer Method ...
(4pi)/3 (R^2-r^2)^(3/2) We basically are being asked to calculate the volume of a spherical bead, that is, a sphere with a hole drilled through it. Consider a cross section through the sphere, which we have centred on the origin of a Cartesian coordinate system, and assuming R gt r: The red circle has radius R, hence its equation is: x^2+y^2=R^2 Method 1 - Calculate core and subtract from ...
the rose region is revolving about the x-axis and y-axis. 1)when the shaded region revolving a bout x-axis. #Volume=piint_a^by^2*dx#
Formula for Volume of a Trapezoidal Prism. If the prism length is L,trapezoid base width B, trapezoid top width A, and trapezoid height H, then the volume of the prism is given by the four-variable formula: V(L, B, A, H) = LH(A + B)/2. In other words, multiply together the length, height, and average of A and B.
Molar volume, or volume of one mole of gas , depends on pressure and temperature, and is 22.4 liters - at 0 °C (273.15 K) and 1 atm (101325 Pa), or STP (Standard Temperature and Pressure), for every gas which behaves similarly to an ideal gas. The ideal gas molar volume increases to 24.0 liters as the temperature increases to 20 °C (at 1 atm). For an ideal gas, the attractive or repulsive ...
The volume of a solid of revolution can be determined by integrating the area of the circles created by the revolution. For a function rotated about the x-axis, the volume is given by \\pi \\int_a^b f^2(x) dx.
