1. Find the molar mass of CF₄:
* Carbon (C) has a molar mass of 12.01 g/mol.
* Fluorine (F) has a molar mass of 19.00 g/mol.
* Since there are four fluorine atoms in CF₄, the total mass of fluorine is 4 * 19.00 g/mol = 76.00 g/mol
* The molar mass of CF₄ is 12.01 g/mol + 76.00 g/mol = 88.01 g/mol
2. Use the formula:
* mass = moles * molar mass
3. Substitute the values:
* mass = 1.36 mol * 88.01 g/mol
* mass = 119.69 g (approximately)
Therefore, the mass of 1.36 mol of carbon tetrafluoride is approximately 119.69 grams.
