The molecular formula is a chemical formula which indicates the exact number of atoms present in the molecule.

The given molecular formula is $C_{3}H_{8}$ and the name of this molecule is propane consist of three carbon atoms which are linked with eight hydrogen atoms by single bonds.

Now, the figure 1 shows the condensed structural formula, figure 2 shows the structural formula and figure 3 shows the skeletal structural formula of propane.

Light travels at a rate of 3.00 x 10^8 m/s. It takes light 8.30 min to travel from the surface of the sun to the earth. What is

bija089 [108]

Answer: The distance of the earth from the sun is $1.494\times 10^{11}m$

Explanation:

Speed of light = $3.00\times 10 ^8 m/s$

Time taken to travel from sun to earth = 8.30 mins = $8.3\times 60=498sec$ (1min=60 s)

As we know ; Speed is defined as the distance travelled per unit time.

$Distance=speed\times time$

Hence distance between sun and earth = $3.00\times 10^8m/s\times 498s=1.494\times 10^{11}m$

Thus the distance of the earth from the sun is $1.494\times 10^{11}m$

Calculate the mole fraction of each component in a solution with 6.87 g of sodium chloride (NaCl) dissolved in 65.2 g of water.

zheka24 [161]

Answer:

mole fraction of NaCl = 0.03145.

mole fraction of water = 0.9686.

Explanation:

Mole fraction is an expression of the concentration of a solution or mixture.

It is equal to the moles of one component divided by the total moles in the solution or mixture.

The summation of mole fraction of all mixture components = 1.

mole fraction of NaCl = (no. of moles of NaCl) / (total no. of moles).

<em>no. of moles of NaCl = mass/molar mass </em>= (6.87 g)/(58.44 g/mol) = 0.1176 mol.

<em>no. of moles of water = mass/molar mass</em> = (65.2 g)/(18.0 g/mol) = <em>3.622 mol.</em>

<em></em>

∴ mole fraction of NaCl = (no. of moles of NaCl) / (total no. of moles) = (0.1176 mol)/(0.1176 mol + 3.622 mol) = 0.03145.

<em>∵ mole fraction of NaCl + mole fraction of water = 1.0.</em>

∴ mole fraction of water = 1.0 - mole fraction of NaCl = 1.0 - 0.03145 = 0.9686.
