Final answer:
Both 1 mole of gold and 1 mole of water contain Avogadro's number of particles, which is 6.022 × 10²³, despite their different molar masses.
Step-by-step explanation:
The question of whether 1 mole of gold or 1 mole of water has more particles can be answered by understanding Avogadro's number and the concept of a mole. Both 1 mole of gold and 1 mole of water contain the same number of particles, which is Avogadro's number, 6.022 × 10²³ particles. The key difference lies in the type of particles; for gold, they are atoms, and for water, they are molecules consisting of two hydrogen atoms and one oxygen atom. However, the mass of 1 mole of gold is greater due to gold's higher molar mass of 196.97 g/mol, compared to water's 18 g/mol, but this does not affect the number of particles.
