Calculate the mass percent composition of lithium in Li3PO4 to four significant figures. Express your answer as a percent.

Li₃PO₄ has 18 % of Li

Explanation:

First of all we determine the molar mass of Lithium phosphate

Molar mass: 115.79 g/ mol

1 mol of lithium phosphate has:

3 moles of Li → 20.82g

The mass percent composition of lithium will be:

(Mass of Li / Total mass) . 100 → (20.82 g / 115.79 g) . 100 = 18 %

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.
