The formula for zinc perchlorate is Zn(ClO4)2. Zn = zinc Cl = chlorine O = oxygen Its molar mass is 264.2812.
The formula mass of magnesium perchlorate (Mg(ClO4)2) can be calculated by adding the atomic masses of magnesium, chlorine, and oxygen in the compound. The atomic mass of magnesium is 24.305 amu, chlorine is 35.453 amu, and oxygen is 16.00 amu. Therefore, the formula mass of magnesium perchlorate is 24.305 + 2(35.453) + 8(16.00) = 223.21 amu.
The gram formula mass of sodium (Na) is approximately 23 grams per mole.
The chemical formula of sodium chloride is NaCl. The formula mass is calculated by adding the atomic masses of sodium (Na) and chlorine (Cl), which are 22.99 g/mol and 35.45 g/mol, respectively. Therefore, the formula mass of sodium chloride is approximately 58.44 g/mol.
The chemical formula of sodium chloride is NaCl; formula is not dependent from the number of moles. Because the molecular mass of NaCl is 57,958 622 382, the mass of 20 moles is 1159,172 447 64.
The formula for sodium perchlorate is NaClO4. To calculate the formula mass, multiply the atomic mass of each element by the number of atoms in the formula and then add them up. The atomic masses are: Na = 22.99 g/mol, Cl = 35.45 g/mol, O = 16.00 g/mol. So, the formula mass of sodium perchlorate is 22.99 + (35.45 x 4) + (16.00 x 4) = 22.99 + 141.8 + 64.0 = 228.79 g/mol.
The formula for zinc perchlorate is Zn(ClO4)2. Zn = zinc Cl = chlorine O = oxygen Its molar mass is 264.2812.
The formula mass of magnesium perchlorate (Mg(ClO4)2) can be calculated by adding the atomic masses of magnesium, chlorine, and oxygen in the compound. The atomic mass of magnesium is 24.305 amu, chlorine is 35.453 amu, and oxygen is 16.00 amu. Therefore, the formula mass of magnesium perchlorate is 24.305 + 2(35.453) + 8(16.00) = 223.21 amu.
