Jet stream- a narrow variable band of a very strong predominantly westerly air currents encircling the globe several miles above the earth.
Sea breeze- a breeze blowing toward the land from the sea, especially during the day owing to the relative warmth of the land.
Land breeze- a breeze blowing toward the sea from the land, especially at night, owing to the relative warmth of the sea.
Ocean current-DescriptionAn ocean current is a continuous, directed movement of sea water generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences.
Gyre-whirl or gyrate.
Coriolis effect-an effect whereby a mass moving in a rotating system experiences a force (the Coriolis force ) acting perpendicular to the direction of motion and to the axis of rotation.
Upwelling-a rising of seawater, magma, or other liquid.
Air mass-a body of air with horizontally uniform temperature, humidity, and pressure.
Front-the side or part of an object that presents itself to view or that is normally seen or used first; the most forward part of something.
Tornado-a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system.
Hurricane-a storm with a violent wind, in particular a tropical cyclone in the Caribbean.

Answer:
6.6253*10²¹molecules of ethane (C₂H₆) are present in 0.334 g of C₂H₆
Explanation:
Avogadro's Number is the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of that substance. Its value is 6.023 * 10²³ particles per mole. Avogadro's number applies to any substance.
In this case, being:
the molar mass of ethane C₂H₆ is:
C₂H₆: 2*12 g/mole + 6* 1 g/mole= 30 g/mole
Then you can apply the following rule of three: if 30 grams of C₂H₆ are present in 1 mole, 0.334 grams of C₂H₆ in how many moles are present?
moles of C₂H₆=0.011
Finally, taking into account the definition of Avogadro's number, you can apply the following rule of three: if there are 6.023 * 10²³ molecules of C₂H₆ in 1 mole, how many molecules are there in 0.011 moles?
molecules of C₂H₆= 6.6253*10²¹
<u><em>6.6253*10²¹molecules of ethane (C₂H₆) are present in 0.334 g of C₂H₆</em></u>
