To calculate the amount of substance (n) of 257 g of lead, you would first need to determine the molar mass of lead, which is 207.2 g/mol. Then, you would use the formula n = mass/molar mass, where n is the amount of substance, and mass is the given mass of lead. Plugging in the values, you would get n = 257 g / 207.2 g/mol = 1.24 mol of lead. Therefore, the amount of substance of 257 g of lead is 1.24 moles. **
