A compound which contains one atom of X and two atoms of Y for each three atoms of Z is made by mixing 5.00 g of X, 1.15 xx 10^(23) atoms of Y and 0.03 mole of Z atoms. Given that only 4.40 g of the compound is formed. Calculate the atomic weight of Y if the atomic weights of X and Z are 60 and 80 amu respectively.

Mass of one atom of X is 6.66xx10^(-23)g . Hence number of mole of atom X in 40kg is

Number of atoms in 12 g of ""_(6)^(12) C is :

Choose the incorrect statement from the following. a) 1 mole Hydrogen atom contains 6.022xx10^23 atoms. b) 1 mole oxygen gas contains 2xx6.022xx10^23 atoms. c) Mass of 1 mole of chlorine is 35.5 g. d) Mass of 0.5 mole of water is 18g. e) 1 mole of nitrogen gas contains 22.4L volume at any state. (Hint: Atomic mass H-1, 0-16, 1-35.5,N=14)

Pick out the correct statements from the following. Also correct the incorrect statements. a) The number of molecules present in 1 mol hydrogen and 1 mol oxygen are same. b) 1 mole chlorine contain 4 xx 6.022 xx10^23 chlorine molecules. c) The mass of 1/2 mol nitrogengas is 14g. d) 0.5 mol water has the mass of 9g. There are 6.022 xx 10^23 H_2 O molecules in it. (Atomic mass H= 1.0= 16, Cl 35.5, N = 14).
