calculate ratio of atoms present in 5g of magnesium and 5g of iron.(atomic mass of mg = 24u, Fe = 56u)​

(a)Explain with the help of a labelled diagram an acitivity for the verification of law of conservation of mass. (b)Find the number of atoms present in 100g of sodium and 100g of iron. (Given that Na=23u, Fe=56u, N_(0)=6.022xx10^(23) per mole)

Which has more number of atoms, 100 grams of sodium or 100 grams of iron (given, atomic mass of Na = 23 u, Fe = 56 u)?

The ratio of moles of atoms in 12 g of magnesium and 16 g of sulphur will be :

Calculate no. of each atom present in 106.5 g of NaCIO_(3^(.)

How many moles are there in 34.5 g of sodium ? (Atomic mass of Na = 23 u )

Calculate the mole ratio of 240 g of calcium and 240 g of magnesium. (Ca = 40 , Mg = 24 u)
