  2. 10.2 Mole–Mass and Mole–Volume Relationships • How can you guess the number of jelly beans in a jar? You estimate the size of a jelly bean and then estimate the dimensions of the container to obtain its volume. In a similar way, chemists use the relationships between the mole and quantities such as mass, volume, and number of particles to solve chemistry problems.

  3. 10.2 The Mole–Mass Relationship • The Mole–Mass Relationship • How do you convert the mass of a substance to the number of moles of the substance?

  4. 10.2 The Mole–Mass Relationship • Use the molar mass of an element or compound to convert between the mass of a substance and the moles of a substance.

  15. 10.2 The Mole–Volume Relationship • The Mole–Volume Relationship • What is the volume of a gas at STP?

  16. 10.2 The Mole–Volume Relationship • Avogadro’s hypothesis states that equal volumes of gases at the same temperature and pressure contain equal numbers of particles.

  17. 10.2 The Mole–Volume Relationship • The volume of a gas varies with temperature and pressure. Because of these variations, the volume of a gas is usually measured at a standard temperature and pressure. • Standard temperature and pressure (STP) means a temperature of 0°C and a pressure of 101.3 kPa, or 1 atmosphere (atm).

  18. 10.2 The Mole–Volume Relationship • At STP, 1 mol or, 6.02  1023 representative particles, of any gas occupies a volume of 22.4 L. • The quantity 22.4 L is called the molar volume of a gas.
