Answer:
2.53 L is the volume of H₂ needed
Explanation:
The reaction is: C₁₈H₃₀O₂ + 3H₂ → C₁₈H₃₆O₂
By the way we can say, that 1 mol of linolenic acid reacts with 3 moles of oxygen in order to produce, 1 mol of stearic acid.
By stoichiometry, ratio is 1:3
Let's convert the mass of the linolenic acid to moles:
10.5 g . 1 mol / 278.42 g = 0.0377 moles
We apply a rule of three:
1 mol of linolenic acid needs 3 moles of H₂ to react
Then, 0.0377 moles will react with (0.0377 . 3 )/1 = 0.113 moles of hydrogen
We apply the Ideal Gases Law to find out the volume (condition of measure are STP) → P . V = n . R . T → V = ( n . R .T ) / P
V = (0.113 mol . 0.082 L.atm/mol.K . 273.15K) 1 atm = 2.53 L

1. The currents in North Pacific gyre rotate more or less clockwise while those of South Pacific rotate counter-clockwise. This is mainly due to the Coriolis effect brought about by the rotation of the earth. Currents above the equator are deflected from west to east while those in the south, east to west.
2. Winds are the main driver of ocean currents because they cause frictional drag on the surface of the oceans in the direction in which the blow. These winds also cause Ekman spirals that are 90 degrees right to the wind direction in the Northern hemisphere and 90 degrees left to the winds in the southern hemisphere.
