Question

Помогите пожалуйста расчитать молекулярную массу Mr(6H2O)​

Answer 1

Рассчитаем относительную молекулярную массу 6 молекул H₂O :

Mᵣ(6H₂O) = 6*(2Aᵣ(H) + Aᵣ(O)) = 6(2*1 + 16) = 6*18 = 108 а.е.м.

Answer 2

Molecular mass of 6H2O can be calculated by adding the molecular mass of 6 water molecules.

The molecular mass of water (H2O) is calculated by adding the atomic mass of two hydrogen atoms (2 x 1.00794) and one oxygen atom (15.9994).

So, the molecular mass of water (H2O) is: 2(1.00794) + 15.9994 = 18.01528

Now, the molecular mass of 6H2O can be calculated as: 6 x 18.01528 = 108.09168

Therefore, the molecular mass of 6H2O is 108.09168.
