Sal is using the ideal gas law which assumes the gases to be ideal. And so, we're going to be B. Yes, if you were dealing with an ideal gas the ideal gas law would still apply which could be used to calculate (in addition to number of moles) temperature, pressure, and volume of the gas. So, we just need to solve for n. So, to solve for n, you just In this video, Sal found the number of moles of air there were. A. D. 25.0%, What is the concentration, in m/v%, of a solution prepared by dissolving 50. g NaCl in a total volume of 2.5 L of solution? B. C. unsaturated. C. condensation. D. 2.0 g, How many milliliters of a 25% (m/v) NaOH solution would contain 75 g of NaOH? The first conversion factor converts from moles of particles to the number of particles. A. C. 10. g We have three here, three B. the units all work out. Given: Number of moles of CH = 8.
