Answer 1

Answer:

the atomic mass of calcium is 40 gram.

first of all we have to calculate the number of calcium atoms present in 1 mole of calcium. this is 6.023 into 10 raise to the part 23 atoms of calcium in 1 mole of calcium. then the mass of one mole of calcium is 6.023 into 10 raise to the power 23 × 40 gram. then the mass of 2 moles of calcium is given by mass of 1 mole of calcium in × 32. this is the required answer.
