34.01468 g/mol
The molar mass of hydrogen is 2 g.
The molar mass of hydrogen sulfide is 34,08 g.
The molar mass of H2Te = 129.61588 g/mol
The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.
hydrogen
Hydrogen sulfide, H2S has a molar mass of 34.08088g/mol.
Hydrogen cyanide, HCN, has a molar mass of 27.03g/mol.
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
The molar mass of hydrogen is 2 g.
1.007947
The molar mass of hydrogen sulfide is 34,08 g.
Sodium has a molar mass of 23 Hydroxide (Hydrogen & Oxygen) have a molar mass of 17 23+17=40g/mol 40grams per mole
The molar mass of H2Te = 129.61588 g/mol
Molar mass of ammonia = (14.01 + 3.03) (Molar mass of nitrogen + 3 times molar mass of hydrogen, as chemical formula of ammonia is NH3). Molar mass= 17.04 Molar mass x moles = mass 17.04 x 3 = 51.12 Mass of 3 moles of ammonia is 51.12g.
The atomic mass of hydrogen is 1u. Atomic mass of bromine is 80u. Therefore, the molar mass of hydrogen bromide is 1+80=81u.
The molar mass of an element is its atomic weight in grams. The molar mass of a molecule or compound is the sum of the subscripts times the molar masses in grams. For example, the molar mass of hydrogen, H, is 1.00794g and the molar mass of oxygen, O, is 15.9994g. The molar mass of water, H2O, is (2 x 1.00794g) + (1 x 15.9994g O) = 18.01528g.
Atomic weight of oxygen is 15,999. Atomic weight of hydrogen is 1,008. Two hydrogen atoms: 2,016. Two oxygen atoms: 31,998. The sum is the molar mass of hydrogen peroxide: 34,014.
