Question

Относительная молекулярная масса 95 будет у вещества? Al2O3 H2O2 BaO MgCl2

Answer 1

Mr(Al₂O₃) = 27·2+16·3 = 102
Mr(H₂O₂) = 1·2+16·2 = 34
Mr(BaO) = 137 +16 = 153
Mr(MgCl₂) = 24 + 35,5·2 = 95
Ответ: у MgCl₂

Answer 2

Relative Molecular Mass of Substances

The relative molecular masses of the given substances are as follows:

- Al2O3: The relative molecular mass of Al2O3 is 101.96. - H2O2: The relative molecular mass of H2O2 is 34.0147. - BaO: The relative molecular mass of BaO is 153.326. - MgCl2: The relative molecular mass of MgCl2 is 95.211.

Therefore, the substance with a relative molecular mass of 95 is MgCl2.
