Calculate the molar mass for citric acid

C₆H₈O₇ = 192 g/mol

Explanation:

Molar mass is the sum of the atomic weight of the atoms present in compound.

Formula of citric acid:

C₆H₈O₇

Atomic weight of hydrogen = 1 amu

Atomic weight of carbon = 12 amu

Atomic weight of oxygen = 16 amu

C₆ = 6 × 12 = 72 g/mol

H₈ = 8 × 1 = 8 g/mol

O₇ = 7 × 16 = 112 g/mol

C₆H₈O₇ = 72 g/mol +  8 g/mol + 112 g/mol

C₆H₈O₇ = 192 g/mol

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
