Question

Read the paragraph carefully and answer the questions: The mass of 1 mole of a substances is equal to its relative atomic mass or molecular mass in grams. The atomic mass of an element gives us the mass of one atom of ythat element in atomic mass unit (u). To get the mass of 1 mole of atom of that element, that is molar mass, we have to take the numerical value but change the units from u to g. Molar mass of atoms is also known as gram atomic mass. For example, atomic of hydrogen =1 u. So gram atomic of hydrogen 1 g 1 u hydrogen has only 1 atom of hydrogen 1 g hydrogen has 1 mole atoms, that is 6.022x10 atoms of hydrogen. i) Write the unified mass and molar mass of Oxygen. ii) Write the number of molecules of water in 18 gm of water.
