The volume of a gas is 450 mL when its pressure is 1.00 atm. If the temperature of the gas does not change, what is the pressure
Fudgin [204]

<u>Ans: 0.225 atm</u>

<u></u>

<u>Given:</u>

Initial volume of gas, V1 = 450 ml = 0.450 L

initial pressure, P1 = 1.00 atm

Final volume, V2 = 2.00 L

<u>To determine:</u>

Final pressure, P2

<u>Explanation:</u>

Based on ideal gas equation:

PV = nRT  ----(1)

where P = pressure, V = volume, n = # moles, R = gas constant, T = temp

Under constant, T and n, eq(1) can be expressed as:

PV = constant

(or) P1V1 = P2V2

P2 = P1V1/V2 = 1.00 atm * 0.450 L/2.00 L = 0.225 atm

Consider the reaction for the combustion of benzene: 2 C6H6(g) 15 O2(g) ---&gt; 12 CO2(g) 6 H2O(l) What mass of H2O is produced
irakobra [83]

Answer: Mass of water produced is 17.3 grams

Explanation:

To calculate the number of moles, we use the equation:

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}      .....(1)

For benzene:

Given mass of benzene = 25.0 g

Molar mass of benzene= 78 g/mol

Putting values in equation 1, we get:

\text{Moles of benzene}=\frac{25.0g}{78g/mol}=0.32mol

The chemical equation for the reaction follows:

2C_6H_6(g)+15O_2(g)\rightarrow 12CO_2(g)+6H_2O(l)

As, oxygen is an excess reagent. Thus benzene is considered as a limiting reagent because it limits the formation of product.

By Stoichiometry of the reaction:

2 moles of benzene produces 6 moles of water

So, 0.32 moles of benzene will produce = \frac{6}{2}\times 0.32=0.96moles of water

Now, calculating the mass of water from equation 1, we get:

Molar mass of water= 18 g/mol

Moles of water = 0.96moles

Putting values in equation 1, we get:

0.96mol=\frac{\text{Mass of water}}{18g/mol}\\\\\text{Mass of water}=17.3g

Thus mass of water produced is 17.3 grams
