You have 15.42g of C2H6. How many moles of H2O can be made?
Amiraneli [1.4K]

<u>Answer:</u> The moles of water produced are 1.54 moles.

<u>Explanation:</u>

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

\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}

Given mass of ethane = 15.42 g

Molar mass of ethane = 30.07 g/mol

Putting values in above equation, we get:

\text{Moles of ethane}=\frac{15.42g}{30.07g/mol}=0.513mol

The chemical equation for the combustion of ethane follows:

2C_2H_6+5O_2\rightarrow 4CO2+6H_2O

By Stoichiometry of the reaction:

2 moles of ethane produces 6 moles of water

So, 0.513 moles of ethane will produce = \frac{6}{2}\times 0.513=1.54mol of water

Hence, the moles of water produced are 1.54 moles.

alex41 [277]

Explanation:

c.

from \\  \frac{P _{1} V _{1} }{T _{1}}  =  \frac{P _{2} V _{2}}{T _{2}} \\ \frac{2 \times 75}{(10+273)}  =  \frac{V _{2} \times 1}{(35+273)}  \\V _{2} =  \frac{2 \times 75 \times (35+273)}{(10+273) \times 1}   \\ V _{2} = 163 \: ml
