The correct answer is   LiCH_{3}CH(CH_{3} )CH_{3} .

<h3>Organometallic reagent</h3>

Organometallic chemistry is the study of organometallic compounds, which are substances that contain at least one chemical bond between a carbon atom from an organic molecule and a metal. These substances include alkali, alkaline earth, and transition metals, as well as metalloids like boron, silicon, and selenium. In addition to links to organyl fragments or molecules, bonds to 'inorganic' carbon, such as those to carbon monoxide (metal carbonyls), cyanide, or carbide, are also typically regarded as organometallic. Although they are not strictly speaking organometallic compounds, some similar compounds, such as transition metal hydrides and metal phosphine complexes, are frequently included in discussions of such substances. The phrase "metalorganic compound," which is comparable but different, describes molecules that contain metals but do not have direct metal-carbon bonds but do have organic ligands.

96.0 g. of a gas occupies 48.0 L at 700.0 mm Hg and 20.0 °C. What is its molecular weight?
g100num [7]

Answer:

I hope this helps 52.2 g/mol

Explanation:

1) Solve for the moles using PV = nRT:

n = PV / RT

n = [(700.0 mmHg / 760.0 mmHg atm¯1) (48.0 L)] / [(0.08206 L atm mol¯1 K¯1) (293.0 K)]

n = 1.8388 mol

2) Divide the grams given (96.0) by the moles just calculated above:

96.0 g / 1.8388 mol = 52.2 g/mol

Temka [501]

Uranium has three common isotopes. The average atomic mass of uranium is 23.7 u/atom.

<h3>What are isotopes?</h3>

Isotopes are similar elements that have a different number of protons.

Uranium has three isotopes

The abundance of 2U has an atomic mass of 233.878 is 0.01%

The abundance of U has a mass of 234.892 amu is 0.71%

The **U has an atomic mass of 237.911 amu is 99.28%

Let's assume we have 10 000 atoms of Uranium

Mass of the 0.01 atoms = 0.01 x 233.878 = 2.33878

Mass of the 0.71 atoms =  0.71 x 234.892 = 166.773

Mass of the 99.28 atoms = 99.28 x 237.911 = 23,619.80

2.33878 + 166.773 + 23,619.80 = 23,788.8

23,788.8 / 1000 = 23.7 u/atom

Thus, the average atomic mass of uranium is 23.7 u/atom.
