The reaction of potassium (K) and water (H2O) is rather explosive, producing hydrogen gas (H2) and potassium hydroxide (KOH). How many moles of hydrogen gas are produced if 25.5 g of potassium and 220 g of water react?
Added by Morgan M.
Step 1
Given: Mass of potassium (K) = 25.5 g Molar mass of potassium (K) = 39.10 g/mol Number of moles of potassium (K) = Mass / Molar mass Number of moles of potassium (K) = 25.5 g / 39.10 g/mol Number of moles of potassium (K) = 0.652 moles Show more…
