1 gram atom of C and 1 gram atom of sulphur have same mass.

Calculate the mass of (a) 1.6 gram atoms of oxygen C (b) 5.6 gram atoms of sulphur c) 2.4 gram atoms of iodine. (Atomic masses : O = 16, S = 32,I = 127)

Which of the following has (i) maximum (ii) minimum mass ? (a) 1 gram atom of C (b) 1 a.m.u. of an atom (c) 1 gram mole of sulphur dioxide (d) 6.02 xx 10^(20) atoms of nitrogen.

Assertion (A): 1 g of O_(2) and 1 g atom of O_(3) have equal number of molecules. Reason (R ): Mass of 1 mol atom is equal to its gram atomic mass.

The number of oxygen atoms in 20gram of sulphur trioxide is the same as those present in the X g of ozone. The atomic mass of sulphur and oxygen are 32u and 16u respectively. Find the value of X.

Which of the following has maximum mass (a) 2.6 gram atoms of sulphur (b) 2.6 gram molecules of sucrose ( C_(12)H_(22)O_(11) ) (c) 2.6 g of iodine

Equals number of atoms are contained in one gram atomic weight of each element and the same number of molecules are found in one gram molecules weight of any compound . The terms gram atomic weight and gram molecular weight are used to refer to a fixed numer(Avogadro's number 6.022xx10^(23)) of particle. the term 'mole' stands for the amount of material which contains these number of particles. If 12 g C^(12) has equal number of atoms as Avogadro's number , what mass of ._(2)He^(4) will contain same number of atoms?

No . of gram atoms in 1kg of Helium
