How many molecules are in 5 moles of C10H210?

Pavlova-9 [17]

Answer:

3.0 x 10²⁴molecules

Explanation:

Given parameters:

Number of moles of compound = 5moles

Unknown:

Number of molecules = ?

Solution:

A mole is substance that contains the Avogadro's number of particles;

1 mole = 6.02 x 10²³ molecules

5 moles of the compound will give 5 x 6.02 x 10²³ molecules

= 3.0 x 10²⁴molecules

6) A volume of 473 mL of oxygen was collected at 27°C. What volume would the oxygen occupy at

sertanlavr [38]

Answer : The volume of oxygen occupy at 173° would be, 703.2 mL

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$

where,

$V_1\text{ and }T_1$ are the initial volume and temperature of the gas.

$V_2\text{ and }T_2$ are the final volume and temperature of the gas.

We are given:

$V_1=473mL\\T_1=27^oC=(27+273)K=300K\\V_2=?\\T_2=173^oC=(173+273)K=446K$

Now put all the given values in above equation, we get:

$\frac{473mL}{300K}=\frac{V_2}{446K}\\\\V_2=703.2mL$

Therefore, the volume of oxygen occupy at 173° would be, 703.2 mL
