How to solve for q thermochemistry
WebVerified questions. A space is at a temperature of 75 F (24 C), and the relative humidity is 45 percent. Find (a) the partial pressures of the air and water vapor, (b) the vapor density, and (c) the humidity ratio of the mixture. Assume standard sea-level pressure. WebThermochemistry - Enthalpy. I found the amount of moles through the molar concentration and found found that all the substances have 0.0352 moles. I then used a table that had the ΔH for each substance and the amount of moles for each substance to use the formula shown in this (timestamp) video. Is this the correct method to solve this problem?
