Answer:
yes that is the name for the formula is magnesium diiodide
First, divide the given mass of lead (ii) chloride by the molar mass of the compound. The molar mass is equal to 278.1 g/mol.
n = m/M
where n is the number of moles, m is the given mass, and M is the molar mass. Substituting the known values,
n = 473.7 g / 278.1 g/mol
n = 1.7 mols
Then, it is to be remember that as per Avogadro, every mol of a substance contains 6.022 x 10^23 formula units.
N = (1.7 mols)(6.022 x 10^23 formula units/mol)
N = 1.02 x 10^24 formula units
Answer: 1.02 x 10^24 formula units
<span>In a cup of salt water, the solvent is water and the solute is the salt. When the two mixed they form a solution. The solvent is what dissolves the solute. It has the largest composition in a solution. The solute has a smaller composition in a solution and it is usually in solid form.</span>
<span>The solubility of a gas decreases with increasing temperature. This is the opposite of water whose solubility increases with increasing temperature. Gases are generally more soluble in colder temperatures. For example, oxygen is more soluble in hot water than cold water. This is why hot water can kill fish due to low oxygen.</span>
