Hydrogen cyanide, HCN, has a molar mass of 27.03g/mol.
To determine the percent composition of carbon in beryllium cyanide, first find the molar mass of beryllium cyanide, then calculate the molar mass contributed by carbon. Finally, divide the molar mass of carbon by the total molar mass of beryllium cyanide and multiply by 100 to get the percent composition.
To find the moles of hydrogen, you can divide the given mass of hydrogen by its molar mass. The molar mass of hydrogen is approximately 1 g/mol. So, moles of hydrogen = mass of hydrogen (in grams) / molar mass of hydrogen (approximately 1 g/mol).
The formula for magnesium cyanide is Mg(CN)2. To find the molar mass, you would add the molar mass of one magnesium atom (24.305 g/mol), and two cyanide ions (26.02 g/mol each). Therefore, the molar mass of magnesium cyanide is 76.345 g/mol.
The molar mass of butane (C4H10) is 58.12 g/mol. The molar mass of hydrogen in butane is 10.81 g/mol. To calculate the mass percent of hydrogen in butane, you would divide the molar mass of hydrogen by the molar mass of butane and multiply by 100. This gives you a mass percent of approximately 18.6%.
The molar mass of hydrogen is approximately 1.008 grams per mole.

The molar mass of hydrogen is 2 g.
CaCl2 = MM(Ca) + 2*MM(Cl) = 40 + 35.5 * 2 =111
To find the percent composition of hydrogen in NH4HCO3, we first calculate the molar mass of the compound. NH4HCO3 has a molar mass of 79.06 g/mol. The molar mass contribution of hydrogen is 1.01 g/mol. To find the percent composition of hydrogen, we divide the molar mass contribution of hydrogen by the molar mass of NH4HCO3 and multiply by 100: (1.01 g/mol / 79.06 g/mol) x 100 ≈ 1.28%.
The molar mass of hydrogen sulfide is 34,08 g.
