Answer (1)
Answer:6. In a chemical reaction, 2 moles of hydrogen gas (H₂) react with 1 mole of oxygen gas (O₂) to form 2 moles of water (H₂O). How many water molecules are formed in this reaction?Since 1 mole contains 6.022 × 10²³ molecules, then:[tex]2 \: moles \: of h_{2}o \: = \: 2 \times 6.022 \times {10}^{23} = 1.2044 \times {10}^{24} molecules[/tex]So, 1.2044 × 10²⁴ molecules of water are formed.
