an element X has a RAM of 10.8. Calculate the vapor density of its chloride XCL3

1 answer

To calculate the vapor density of XCl3, we need to know the molar mass of X (element X) and the molar mass of XCl3.

Given that the relative atomic mass (RAM) of X is 10.8, we can assume it refers to the molar mass in grams per mole.

To calculate the molar mass of XCl3, we need to know the molar mass of chlorine (Cl). The molar mass of Cl is approximately 35.45 g/mol.

Now, we can calculate the molar mass of XCl3. Since XCl3 has three chlorine atoms, the molar mass of XCl3 is calculated as:
(10.8 g/mol) + 3*(35.45 g/mol) = 116.65 g/mol

The vapor density of a substance is defined as the ratio of its molar mass to the molar mass of hydrogen (H2). The molar mass of hydrogen is approximately 2.02 g/mol.

Therefore, the vapor density of XCl3 is calculated as:
116.65 g/mol / 2.02 g/mol = 57.83

So, the vapor density of XCl3 is approximately 57.83.
