1 atm or 762 torr). If the value of vapor pressure were not temperature-dependent, it would be difficult to get any liquids (or solids) to boil, or evaporate, especially those with high inherent vapor-pressure values.
To find the molar mass of the solute, refer to a periodic table. If the solute is a single element, calculate the molar mass of that element. If it consists of a more than one element (i.e. a compound) calculate the molar mass of the compound. Every element has a different molar ...
How to Calculate the Stoichiometric Ratio. Stoichiometry is a type of math associated with chemistry. In stoichiometry, you perform calculations pertaining to moles (the basic unit of weight in chemistry), masses and percentages. A stoichiometric ratio s
Calculate the temperature of a gas if 0.5 moles occupy 1.2 dm3 at a pressure of 200 kPa. Rearrange the following law equation: p1v1/t1 = p2v2/t2, to obtain formulas for t2 and v1, respectively. How do you work through the following equation? 4.00 atm x 8.00 L = P2 x 2....
