What is the molar mass of citric acid (C6H8O7) and baking soda (NaHCO3)?

Chemistry
1 answer:
Mama L [17]3 years ago
4 0

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>

What are some compare and contrasts between Terrestrial Planets and Gas Planets?
dexar [7]
<h3><u><em>The different types of planets would be the gas giants all have more than 12 moons whereas the terrestrial planets all have less than 3 moons. A second difference is that that gas giants are all larger in diameter than the terrestrial planets. Also the Gas Giants are usually bigger than Terrestrial Planets. Gas Giants also have thicker atmospheres, and have gaseous surfaces. Terrestrial planet tend to be smaller, and have solid surfaces. In our solar system, Mercury, Venus, Earth (home), and Mars are Terrestrial planets.I am glad to help anytime ...Brainliest?</em></u></h3>

Suppose you were given a substance and asked to determine weather or not it was a plasma. Write the characteristics you would lo
Sphinxa [80]

Electrical conductivity, electromagnetism, and temperature are the features that one would look for in order to determine plasma. Plasma refers to a hot ionized gas possessing high electrical conductivity. It is electrically neutral with negative and positive particles. It can be considered the most abundant form of matter in the universe.  

The features of plasma are substantially distinct from those of the usual neutral gases so that plasmas are regarded as a different fourth state of matter.

Answer:

C. the relative molecular mass of the compound

Explanation:

Like molecular formulas, empirical formulas are not unique and can describe a number of different chemical structures or isomers. <u>To determine an empirical formula, the relative molecular mass of the composition of its elements</u> can be used to mathematically determine their ratio.
