Could someone help with as many of these as they can? 1.how many moles of h20 are needed to make 0.82 moles of NaOH
2. if a reaction used 22.6g of Na2O how many moles of H2O are needed to react with it
3. how many grand of NaOH would be formed by placing 3.64g of Na2O in excess water​

where are the choice options?

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

what is the question here. i think you messed up.
