What is the molar mass of lead ll iodide?
The molar mass of lead(II) iodide (PbI₂) can be calculated by summing the atomic masses of its constituent elements. Lead (Pb) has an atomic mass of approximately 207.2 g/mol, and iodine (I) has an atomic mass of about 126.9 g/mol. Therefore, the molar mass of PbI₂ is calculated as follows: 207.2 g/mol (for Pb) + 2 × 126.9 g/mol (for the two I) = 460.1 g/mol. Thus, the molar mass of lead(II) iodide is approximately 460.1 g/mol.

How many grams are in 0.02 moles of beryllium iodide BeI2?
To find the mass in grams of 0.02 moles of beryllium iodide (BeI₂), we first calculate its molar mass. The molar mass of beryllium (Be) is approximately 9.01 g/mol, and iodine (I) is about 126.90 g/mol. Thus, the molar mass of BeI₂ is 9.01 + (2 × 126.90) = 262.81 g/mol. Therefore, 0.02 moles of BeI₂ would weigh approximately 0.02 × 262.81 = 5.26 grams.

Calcium iodide has the chemical formula CaI2. To find the percent composition, calculate the molar mass of CaI2, then find the molar mass contributed by each element (calcium and iodine). Finally, divide the molar mass contributed by each element by the total molar mass of CaI2 and multiply by 100 to get the percent composition.
What is the percentage of iodine in potassium iodide?
The percentage of iodine in potassium iodide can be calculated using the formula: (molar mass of iodine / molar mass of potassium iodide) x 100. The molar mass of iodine is approximately 126.9 g/mol, and the molar mass of potassium iodide is approximately 166 g/mol. Therefore, the percentage of iodine in potassium iodide is (126.9 / 166) x 100 = 76.5%.
