What is the chemical formula and the formula mass for barium chloride?
The chemical formula of barium chloride is BaCl2.The molecular mass is 208,23 g (for the anhydrous salt).
How many formula units make up 21.2g of magnesium chloride Mg Cl 2?
To calculate the number of formula units in 21.2g of magnesium chloride (MgCl2), first calculate the molar mass of MgCl2 which is 95.21 g/mol. Then, divide the given mass by the molar mass to get the number of moles (0.223 mol). As there is one mole of MgCl2 in 1 formula unit, 0.223 mol is equal to 0.223 formula units.
How many formula units make up 25.2 g of magnesium chloride?
To determine the number of formula units, you need to first calculate the molar mass of magnesium chloride (MgCl2). The molar mass is 95.21 g/mol. Next, divide the given mass (25.2 g) by the molar mass to find the number of moles of magnesium chloride. Finally, use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
What is chemical formula mass of sodium chloride?
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.
What is the mass defect of lithium-7 Assume the following Atomic number of lithium 3 Atomic mass of lithium 7.016003 atomic mass units. Mass of 1 proton 1.007276 atomic mass units. Mass of 1 neutron 1?
To calculate the mass defect of lithium-7, we use the formula: Mass defect = (mass of protons + mass of neutrons) - mass of lithium-7. Given that lithium-7 has 3 protons and 4 neutrons, the total mass of protons is 3 x 1.007276 = 3.021828 amu, and the total mass of neutrons is 4 x 1 = 4 amu. Therefore, the total mass of protons and neutrons is 3.021828 + 4 = 7.021828 amu. The mass defect is then 7.021828 - 7.016003 = 0.005825 amu.
What is the formula mass of beryllium chloride?
The formula for beryllium chloride is BeCl2. To calculate the formula mass, you need to add the atomic masses of beryllium and chlorine. The atomic mass of beryllium is about 9 and the atomic mass of chlorine is about 35.5. Therefore, the formula mass of beryllium chloride is approximately 9 + (2*35.5) = 80 grams per mole.
The formula for lithium bromide is?
The formula for lithium bromide is LiBr. The compound has a molar mass of 86.845 grams per mole. One of its main uses is as a desiccant.
What is the chemical formula and the formula mass for barium chloride?

What is the mass defect of lithium-7 Assume the following Atomic number of lithium 3 Atomic mass of lithium 7.016003 atomic mass units. Mass of 1 proton 1.007276 atomic mass units. Mass of 1 neutron 1?
To calculate the mass defect of lithium-7, we use the formula: Mass defect = (mass of protons + mass of neutrons) - mass of lithium-7. Given that lithium-7 has 3 protons and 4 neutrons, the total mass of protons is 3 x 1.007276 = 3.021828 amu, and the total mass of neutrons is 4 x 1 = 4 amu. Therefore, the total mass of protons and neutrons is 3.021828 + 4 = 7.021828 amu. The mass defect is then 7.021828 - 7.016003 = 0.005825 amu.
