That means that 8.23 Ã10-3 mol of MgO is formed and is. composed of 8.23 Ã10-3 mol of Mg and 8.23 Ã10-3 mol of O. So the mass of MgO is 0.332 g Notice that I. use unit. analysis. 8.23 Ã10-3 mol of O has a mass of (8.23 Ã10-3 mol) Ã. (16.0 g/mol) = 0.132 g.

Outside of the cat family, retractable claws are found only in certain species of the Viverridae (and the extinct Nimravidae). A claw that is retractable is protected from wear and tear. Most cats and dogs also have a dewclaw on the inside of the front paws. It is much less functional than the other claws but does help the cats to grasp prey. Because the dew claw does not touch the ground, it receives less wear and tends to be sharper and longer.
