How many moles of Io3 are present in a 100mL solution containing 1.390g of KIO3
1 answer
How many moles KIO3 do you have in 1.390 g KIO3. moles = grams KIO3/molar mass KIO3. Ignore the 100 mL. It has nothing to do with the problem. Now you know there is 1 mole IO3^- ions in 1 mole KIO3 and you know moles KIO3. so......
