This video tutorial explains how to convert moles of copper(II) sulfate pentahydrate (CuSO4·5H2O) to grams. It begins by introducing the concept of conversion and the importance of molar mass. The video details the calculation of the molar mass of CuSO4·5H2O, including the addition of water molecules. It then demonstrates the conversion process by multiplying moles by the molar mass to obtain grams. The tutorial also covers the reverse process of converting grams to moles by dividing by the molar mass. The video concludes with a practical example and a link for further assistance.
