What is its volume at STP?

1) look up standard temperature and pressure\n2) use PV = mRT with the given conditions to find the mass of helium\n3) use PV = mRT, with the mass you found above and the standard temperature and pressure to solve for V.\n\n*note:  Make sure you are using the correct gas constant, R, for helium.  Either look it up, or use R = R_univarsal/Molar weight.

if i remember my chemistry right, a mole of gas at stp is 22.4 liters, so the answer should be E), 2 moles

Volume = pi*r^2*h\n\nWhere pi = 3.14.159...\nr = raduis of cylinder in feet\nh = height of cylinder in feet

291.13 L is the correct volume.\n\nCheck your algebra when you are solving for V1.

area or volume???\n\narea = 2 (3.4 * 3 + 3*2.2 + 2.2*3.4 )\n in square meters.\n\nvolm = 3.4*3*2.2\nin cubic meters.\n\n\nI only edited bcoz ever1 is giving wrong ans for area. Correct area is 48.56 sq mtr. I dont understand how it can b 6.6\n\nvolm = 22.44 cubic mtr

Measurements (In distance I'm assuming) would give you volume.\n\nMass / Volume = Density\n\nIf you have volume & density, you can rewrite the equation:\n\nMass = Volume * Density

hi chuck, \n\n5300 lbs of pressure?  yikes!  hate to be working near that thing if it should blow!\n\nanyway the point of a bladder accumulator is to expand/contract thereby absorbing transient fluctuations in the pressure, right?  so i would expect you would want it to be somewhere near the middle of its range - too empty and it won't be full enough to compensate for pressure dips, and too full and it won't be able to expand to handle pressure spikes.  so somewhere near halfway i.e. 60% sounds reasonable to me.  \n\nthis is one of those things where a calculation of the pressure depends on a LOT of weird variables like the elastic constant of the bladder, the shape of it etc.  your best bet to get maximum damping is probably to just do an empirical trial and error sort of thing.\n\n200 Hz is well within the audible range of the human ear.  G3 on the piano (find middle A, go down an octave plus one white key - that's low G) is supposed to be tuned to 196 Hz, so your 200 cps hum should sound almost like low G.  depending on the amplitude of the pulses you could probably just listen to the pipes, or use a stethoscope if it's too quiet, and then vary the charge pressure looking for a minimum in the hum.\n\ngood luck!

Volume of a shphere  = 4/3 * pi * R^3\n\nwhere pi = 3.142 (approx)\nand R is the radius

STP is 0 Celsius and 760 mm Hg.  \n\nNTP is 20 Celsius and 760 mm Hg.

100g O2 x (1 mole O2)/(32g O2) x (22.4 L O2 @ STP)/(1 mole O2 @ STP) x (1/1.5) x (298/273)\n\n= 50.9 L\n\nThe 22.4 L = 1 mole is only true @ STP.  The higher pressure reduces that volume and the higher temperature increases it.

If you want to measure the volume of sound, it is measured in decibles.\n\nIf you want to measeure the width or band or sound it is measured in Hertz or mega hertz. For this you need an oscilla scope.

STP is the same for every element and compound -- one atmosphere pressure (14.7 psi, 760 torr) and 0°C.\n\nSo, what is your question about dimethyl ether at STP?\nIt is a gas at STP.  MW 46.07 g/mole.  BP = -25°C.  MP = -138.5°C.

Ok.... \nfirst: 1atm = 760 torr\n Now, as per the gaseous  STP conditions., 1 mole of oxygen will occupy 22.4 lit volume at STP conditions.\nSTP: T=273K\n        P= 760 torr\n       V =22.4 lit\n       Mass of O2 at STP = 32g\n\nNow. second set of conditons:\n P2= 1400 torr\nT2 =41 K\nMass= ?\n\nPV = nRT\nPV = (w/Mwt) XRT\n\nP1/w1T1 = (P2 /W2 T2)\n\nSubstitute these values;;\nW2= 392g of oxygen.\n\nIs the solution is clear enough?
