If y varies directly as x, and y is 400 when x is r and y is r when x is 4, what is the numeric constant of variation in this relation? (a) 10 (b) 40 (c) 100 (d) 198 If y varies directly as x, and y = 30 when x = 4, how do you find the constant of proportional...
Assuming the cylinder is rigid and doesn't expand when filled with oxygen, we can use the ideal gas law to calculate the mass of oxygen in the cylinder:PV = nRT where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant, and T...
The Boltzmann constant has a major role in today’s discoveries and innovations. It is directly connected to absolute temperature and average kinetic energy. It has a popular value of 1.3806452 x 10−23 with units of Joule per Kelvin as stated in the International System of Units. However, ...
How many moles of oxygen gas must be in a 12.2 L container to exert a pressure of 0.877 atm at a temperature of 35.0 degree C (the ideal gas constant, in this case, is 0.0821 L atm/mole K)? A 45.0 L container holds 38.0 mole...

For gases, pressure is discussed in terms of temperature, volume, and the number of gas particles, and for this, we use the ideal gas law: PV=nRTPV=nRT In this equation, P is the pressure, V is the volume, T is the temperature, R is the ideal gas constant, and n is the amount...

a gas is a function of both pressure and temperature. At STP, 1 mol of gas occupies 22.4 liters (L) of volume. In other words, the molar volume of a gas at STP is 22.4 L. This volume can be found using the ideal gas law: PV=nRT (n = number of moles, R = gas constant)....
n = moles of the substance (mol) (it's a number that is dependent on the molecular weight of a substance) R = gas constant = 0.0821 L-atm/mol-K T= temperature in Kelvin (K) To solve for temperature, you rearrange the equation (pV = nRT) above to get temperature by itself. So,...
