The molar mass of a substance/chemical is the mass of the sample substance divided by the amount of substance in that sample.
Explanation:
- In order to calculate the atomic mass of a substance we first obtain the atomic weight of the substance from the periodic table.
- Then we count the number of atoms of the substance and multiply it with the individual atomic mass.
Molar mass of Citric Acid ( H3C6H5O7) is 192.1235 g/mol
It is calculated as :
Molar mass of C₆H₈O₇ = 6(atomic mass of C) + 8(atomic mass of H) + 7(atomic mass of O) = 6(12.0 g/mol) + 8(1.0 g/mol) + 7(16.0 g/mol) = 192.0 g/mol.
Molar mass of baking soda (NaHCO₃) is 84.0 g/mol
Molar mass of NaHCO₃ = (atomic mass of Na) + (atomic mass of H) + (atomic mass of C) + 3(atomic mass of O) = (23.0 g/mol) + (1.0 g/mol) + (12.0 g/mol) + 3(16.0 g/mol) = 84.0 g/mol.
The milk of magnesia is a
suspension of magnesium hydroxide in water, which is a strong base that is used
to neutralize excess stomach acid. The presence of stomach acid or hydrochloric
acid (HCl) that is known to be a strong acid will react with the strong base and
neutralization reaction occurs since conjugate partners produced negligible
strength where the products are a salt and water.
Answer:
Legend has it that Mendeleev conceived and created his table in a single day: February 17, 1869, on the Russian calendar (March 1 in most of the rest of the world).READ THE EXPLANATION
Explanation:
La leyenda dice que Mendeleev concibió y creó su mesa en un solo día: 17 de febrero de 1869, en el calendario ruso (1 de marzo en la mayoría del resto del mundo).
