Bob just filled his car's gas tank with 20 gallons of gasohol, a mixture consisting of 5% ethanol and 95% gasoline. If his car r
WARRIOR [948]

Answer:

C. 10/9 gallons

Explanation:

Given that

V= 20 gallons

Volume of ethanol = 5% of V = 0.05 x 20 = 1 gallons

Volume of the gasoline = 95 % of V = 19 gallons

Lets take x gallons of ethanol is added to achieve optimum performance.

(1+x)/(20+x) = 10 %

(1+x)/(20+x) =0.1

1+ x = 0.1 ( 20+ x)

1+ x = 2 + 0.1 x

1 = 0.9 x

x= 10 /9  gallons

So the option C is correct.

C. 10/9 gallons

0.556 g of a solid white acid are dissolved in water and completely neutralized by the addition of 52.38 mL of 0.396 M NaOH. Cal
Veseljchak [2.6K]

Answer:

M_{acid}=26.804g/mol

Explanation:

Hello,

In this case, by knowing that the used NaOH equals in moles the acid (monoprotic) as shown below, during the titration:

n_{acid}=n_{NaOH}

By knowing the volume and the concentration of the NaOH, one obtains:

n_{acid}=0.05238L*0.396\frac{mol}{L}=0.0207mol

Thus, the molar mass of the acid is computed based on the previously computed moles and the given mass as follows:

M_{acid}=\frac{m_{acid}}{n_{acid}}=\frac{0.556g}{0.0207mol}=26.804g/mol

Best regards.
