Consider this chemical reaction: Sn + NaOH → Na ₂SnO ₂+ H ₂. How many moles of hydrogen are liberated from the complete reaction of 3.47 × 10 ⁴kg of tin metal in excess sodium hydroxide?

Question

Quizplus · Accepted Answer

The molar mass of tin (Sn) is approximately 118.71 g/mol. First, convert the mass of tin to moles: 3.47 × 10^4 kg = 3.47 × 10^7 g. Moles of Sn = 3.47 × 10^7 g / 118.71 g/mol ≈ 2.92 × 10^5 moles. The balanced reaction shows a 1:1 ratio between Sn and H2, so 2.92 × 10^5 moles of hydrogen are liberated.
