By the Balanced eqn

60g ethane requires 7x32= 224g oxygen

here ethane is in excess.oxygen will be fully consumed

hence

300g oxygen will consume  

60

⋅

300

224

=

80.36

g

ethane

leaving (270-80.36)= 189.64 g ethane.

By the Balanced eqn

60g ethane produces 4x44 g CO2

hence amount of CO2 produced =

4

⋅

44

⋅

80.36

60

=

235.72

g

and its no. of moles will be  

235.72

44

=5.36 where 44 is the molar mass of Carbon dioxide

hope this helps

dybincka [34]

Answer:
1. x=4
2.x=\frac{57}{7}
3.x=\frac{27.7}{11}

Explanation:

Given the following questions:

12=3x
7x=57
11x=27.7

In order to find the answers to these questions, we have to recognize that in order to isolate the variable we need to divide on both sides.

Question one:
12=3x
\frac{3x}{3} =\div3
12\div3=4
x=4

Question two:
7x=57
\frac{7x}{7} =\div7
57\div7=8.14285714=\frac{57}{7}
x=\frac{57}{7}

Question three:
11x=27.7
\frac{11x}{11} \div11
27.7\div11=2.51818182=\frac{27.7}{11}
x=\frac{27.7}{11}

Hope this helps.
