At a cost of $1600/oz, how much would you have to pay for a solid cubic foot of gold?
Alex777 [14]
<h3>You will pay $ 30876800</h3>

We'll begin by calculating the mass in ounce (oz) of a cube foot (ft³) of gold. This can be obtained as follow:

<h3 />

Density of gold = 19298 oz/ft³

Volume of gold = 1 ft³

<h3>Mass of gold =?</h3>

Density = mass /volume

19298 = mass / 1

<h3>Mass of gold = 19298 oz</h3>

Finally, we shall determine the cost of 19298 oz of gold. This can be obtained as follow:

1 oz = $ 1600

Therefore,

19298 oz = 19298 × 1600

19298 oz = $ 30876800

Therefore, a solid cube foot of gold (i.e 19298 oz) will cost $ 30876800

stearic acid and linoleic acid stearic acid and linoleic acid stearic acid has the higher melting point, because it has two more
elena55 [62]

Acid palmitic acid has higher melting point, because it has two more methylene groups.

\text { Myristic acid } \rightarrow \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{12} \mathrm{COOH} \\& \text { Palmitic acid } \rightarrow \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{14} \mathrm{COOH} \\

Acid palmitic acid has higher melting point, because it has two more methylene groups.

Giving it a greater surface area and therefore more intermolecular  van der waals interact than the myristic acid.

stearic arid \mathrm{CH}_3\left(\mathrm{CH}_2\right)_{16} \mathrm{COOH}

linoleic acid \mathrm{C}_{18} \mathrm{H}_{32} \mathrm{O}_2 (two double bond)

Stearic acid has higher Melting point, because it does not have any Carbon-Carbon double bonds, whereas linoleic acid has two cis double bonds which prevent the molecules from packing closely together.

Oleic Acid and Linoleic acid.

\mathrm{C}_{18} \mathrm{H}_{34} \mathrm{O}_2-one double bond (cis)

Acid palmitic acid has higher melting point, because it has two more methylene groups.

How many stereoisomers are possible for 1 2-dichlorocyclopentane?
slega [8]
<span>There are only three stereoisomers of 1,2-dimethylcyclopentane. As there are only two chiral carbons, so the maximum number of stereoisomers is 4, but two are the same meso-compound which means that there are only 3.</span>
