Answer:

0.025536g

Explanation:

no. of mole = mass/Mr

mass = Mr ×  no. of mole

         = [23 + 1 + 12 + 3(16)] × 3.04×10^-4

         = 0.025536g

Thermohaline currents are influenced by wind.<br><br> True or false?
tresset_1 [31]

Answer:

FALSE

Explanation:

The under-water deep ocean currents that are generated due to the differences in the water density are generally termed as the thermohaline circulation. It is mainly controlled by the two factors namely the temperature and the salinity. The word 'thermohaline' is directly derived from the temperature (thermo) and salinity (haline).

This thermohaline circulation is considered as the oceanic conveyor belt that allows the water to move under the surface of water at certain depths from the equator to the poles and back from the poles to the equator.

Thus, it is directly associated with the density of the water. It has no relation with the wind.

Hence, the above statement is False.
