Aug 10, 2022 · Learning Objectives. Perform conversions between mass and moles of a substance. Convert from mass or moles of one substance to mass or moles of another substance in a chemical reaction. Use a balanced chemical equation to determine molar relationships between substances.
The volume of one mole of any gas at room temperature and pressure (20℃ and 1 atmosphere pressure) is 24 dm³. Reacting mass calculations can use a combination of mass to volume calculations and vice versa. Amount of substance (moles) can be calculated using multiple equations.
7. Convert the following two-step quantities, converting first to moles and then to the desired quantity. a. Find the number of molecules in 60.0 g of N 2 O. 8.21 x 10 23 molecules b. Find the volume of 3.24 x 1022 molecules of Ne 1.21 L c. Find the mass of 18.0 L of CH 4 12.9 g d. Find the volume of 835 g of SO 3 234 L e.
Using molar volume, convert the following quantities. a. 5.40 mol O2 (121 L) . b. 3.20 x 10–2 mol CO2 (0.717 L )
Molar mass tells us the mass of 1 mol of an atom or compound. In each case we simply calculate the sum of the masses of the atoms in the formula to determine the mass of a mole. These masses can be found on the periodic table. EXAMPLE: Calculate the molar mass of a mole of iodine, I2.
