In the lab, your supervisor asked you to prepare 1 liter of 0.5 M NaH2PO4 (sodium phosphate monobasic) solution. In the chemical cabinet of the lab, however, you only found a bottle of sodium phosphate monobasic monohydrate, NaH2PO4.H2O (FW = 138.0). In this case, you should weigh out .0 g of NaH2PO4.H2O to make 1 liter of the solution. Next day, a graduate student in the lab asked you to prepare 1 liter of solution X, following the lab recipe. The lab recipe book says you should dissolve 240 g of NaH2PO4 (anhydrous) in water to make 1 liter of solution X. However, the lab seems to have only NaH2PO4.H2O (monohydrate) in the chemical cabinet and you cannot find anhydrous NaH2PO4 powder anywhere. In this case, you should use .0 g of NaH2PO4.H2O to make 1 liter of solution X. I know these are review questions, but I have no idea how to do it because it throws in the h20. anyone can help?
