96.08462 grams 96.08462 grams/mole The formula mass of a substance is simply the sum of the atomic weights of the atoms in the substance. So let's start by looking up the atomic weights. Atomic weight nitrogen = 14.0067 Atomic weight hydrogen = 1.00794 Atomic weight carbon = 12.0107 Atomic weight oxygen = 15.999 Looking at the formula (NH4)2CO3, we have 2 nitrogen, 8 hydrogen, 1 carbon, and 3 oxygen atoms. So the formula mass is: 2 * 14.0067 + 8 * 1.00794 + 12.0107 + 3 * 15.999 = 96.08462 grams And conveniently, the molar mass of a substance is exactly the same as the formula mass. So it too is 96.08462 grams/mol
Magnesium is more metallic than chlorine because elements with metallic character readily lose electrons. Magnesium has an ionic charge of +2, ie. it will lose 2 electrons if possible. Chlorine has an ionic charge of -1, means that it will gain 1 electron if possible.
Scientists are able to understand Earth's interior by studying seismic waves. These are waves of energy that travel through Earth, and they move similarly to other types of waves, like sound waves, light waves, and water waves.
