Flashcards do conjunto (7)
- 1How do you find the mass of one mole of a compound?Add up all the relative atomic masses of the elements of the compound
- 2What is Avogadro's Law?The same volume of gas
contains the same number of particles.
It does not matter what gas you have,
they all contain the same number of particles
provided that they are at the same temperature and pressure. - 3What does one mole of a gas at room temperature and pressure equal?24,000 cm3 or 24dm3
- 4How do you create a chemical or symbol equation?First write down the word equation. Then write down the symbols and formulae. After, balance the equation.
- 5How can the number of moles of a gas be calculated?Number of moles of a gas = Volume of gas/Volume of a mole
- 6How can moles be measured in a solution?Number of moles = Volume of solution (cm3) x mol/dm3/1000
- 7What is a mole?The
number of atoms in exactly 12 grams of 12C (carbon twelve).
