given atomic mass of calcium =40g
40g of calcium =6.022×10²³ atoms
1 gram of calcium = 6.022×10²³÷40
atoms
2 gram of calcium = 6.022×10²³×2÷40 atoms
2 gram of calcium =0.3011×10²³ atoms
40g of calcium =6.022×10²³ atoms
1 gram of calcium = 6.022×10²³÷40
atoms
2 gram of calcium = 6.022×10²³×2÷40 atoms
