The number of atoms in 7.5 grams of sodium chloride is 1.55X10^23. Sodium chloride is more commonly known as salt or table salt.
The gram-molecular mass of H2O is 18.01. Therefore, 75.0 grams contains 75.0/18.01 = 4.16 moles. Each molecule contains two hydrogen atoms. Therefore, the number of hydrogen atoms = 2(4.16)(6.022 X 1023) = 5.01 X 1024 atoms.
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
75g is 75g
The number of stones in 75g would depend on the average weight of a stone. However, to give you an estimate, an average stone weighs around 5g. So, approximately, 75g would be equivalent to 15 stones.
