Question

How many moles are in 25 grams of HF

Answer 1

Suppose 25 L to be 25 kg water (almost, -0.2% at room temperature) then divide 25,000 g by the moalr mass of H2O being 2+16=18 g/mole you get = 1385 moles (because 1 mole = 18 grams)

Answer 2

Using this equation, we can take 25/(1.0 + 19) and find that it is equal to 1.25 moles.
