Hi myself Shrushtee.
Explanation:
Ocean water is constantly moving, and not only in the form of waves and tides. Ocean currents flow like vast rivers, sweeping along predictable paths. Some ocean currents flow at the surface; others flow deep within water. ... Tides contribute to coastal currents that travel short distances.

Answer:
80.2
Explanation:
we subtract 18.2 from the total percentage which is 100%
Use equation:
PV = nRT
1.4*V = 1*0.082057*332
V = 27.24/1.4
V = 19.46L
Molar mass H2S = 2+32 = 34g/mol
34g H2S has volume 19.46L
Density = mass / volume = 34/19.46 = 1.75 g/L
