So there are a lot of steps and conversions to this problem that I'll try to explain.
First, this is an ideal gas law problem, so you use the equation PV=nRT, where P is pressure in kPa, V is volume in liters, n is the amount of gas in moles, R is the gas constant, and T is temperature in Kelvin.
Then, you realize everything they gave you is in different units, meaning everything has to be converted. 760 torr is equivalent to 101.3 kPa, which is used as a conversion factor. Celsius to Kelvin is just adding 273. The volume is found by finding the volume of the cylinder using pi×(r^2)×h (but you also have to make sure your units are the same since one of the measurements they give you is in meters and the other in centimeters). Then, since you need it in liters, convert that as well, knowing that 1000cm^3 is equivalent to 1 L.
Plug everything into the ideal gas law equation.
Then, since it asks for grams and not moles, you'll need to do one more conversion using the molar mass of neon (on the periodic table) to find the mass is about 0.005 grams.
Answer:
Pentane reacts with oxygen in a combustion reaction to produce carbon dioxide and water. C5H12 + O2 -> CO2 + H2O If you have 5.00 moles of pentane, how many moles of water will be produced? Hexane combusts in the presence of oxygen to produce carbon dioxide and water.
Explanation:
Answer:
58.92 g EDTA
Explanation:
315.1 mL = .3151 L
M = Moles / Liter
.3151 L x <u>0.5 mol EDTA</u> x <u>374 g EDTA</u> = 58.92 g EDTA
1 L EDTA 1 mol EDTA
