Chapter 11: Q. 11.74 (page 395)

Margarines are produced from the hydrogenation of vegetable oils, which contain unsaturated fatty acids. How many grams of hydrogen are required to completely saturate $75.0$ g of oleic acid, $C_{18} H_{34} O_{2}$ which has one double bond?

Short Answer

Expert verified

The amount of hydrogen required will be $0.53 g$ .

Step by step solution

Given Information

We are given the amount of oleic acid and we have to find out how many hydrogen atoms are required to completely saturate the oleic acid.

Explanation

As the $75.0 g$ of oleic acid is given which means,

$N u m b e r o f m o l e s = \frac{G i v e n m a s s}{M o l a r m a s s} = \frac{75.0}{282.46}$

which gives moles arelocalid="1652813214819" $0.265$ .

Now, for one double bond, we require one mole of $H_{2}$

which states that $0.265$ moles of oleic acid require a $0.265$ mole of $H_{2}$ .

given mass = localid="1652813375751" $0.265 \times 2 = 0.53$ g

Hence, $0.53 g$ of hydrogen is required.
