1- An aqueous solution of glucose is labelled as 10% by mass (w/w) , if the density of the solution is 1.2 g/ml . Calculate the molartiy ,molality and mole fraction of each component ?
2- A 14.53 M ammonia solution contains 28% ammonia by mass. Calculate the density of the solution.
3- Calculate the mass of CO2 which contains the same number of molecules as are contained in 40 gram of oxygen.
4- 9.7 * 10^17 atoms of iron as much as 1g of H2 at STP. What is the atomic mass of iron ?
5- Express the value of density of water in kg/m^3(given density of water= 1g/cc)
