Answer:
1. 192.0 g/mol.
2. 84.0 g/mol.
Explanation:
- <em>The molar mass is the mass of all the atoms in a molecule in grams per mole.</em>
- <em>To calculate the molar mass of a molecule, we first obtain the atomic weights from the individual elements in a periodic table. We then count the number of atoms and multiply it by the individual atomic masses.</em>
<em></em>
<em>1. Molar mass of citric acid (C₆H₈O₇):</em>
<em>Molar mass of C₆H₈O₇ = 6(atomic mass of C) + 8(atomic mass of H) + 7(atomic mass of O)</em> = 6(12.0 g/mol) + 8(1.0 g/mol) + 7(16.0 g/mol) = <em>192.0 g/mol.</em>
<em>2. Molar mass of baking soda (NaHCO₃):</em>
<em>Molar mass of NaHCO₃ = (atomic mass of Na) + (atomic mass of H) + (atomic mass of C) + 3(atomic mass of O) </em>= (23.0 g/mol) + (1.0 g/mol) + (12.0 g/mol) + 3(16.0 g/mol) = <em>84.0 g/mol.</em>

After oil is naturally refined underground, the only way that a viable deposit of hydrocarbon can form is if the oil encounters some kind of trap.
No two electrons in an atom<span> can have exactly the same </span>quantum<span> numbers. Orbital </span>quantum<span> numbers tell you what energy level the electron is in. In the Bohr</span>model<span>, this represents how high the orbit is above the nucleus; higher orbits have more energy</span>
