How many moles of calcium hydroxide (ca(oh)2) are in 165 grams of ca(oh)2?

The amount of a substance can be converted into grams of that substance by using the molar mass. It is a physical property of a substance which describes the mass per mole of the substance. The molar mass of Ca(OH)2 is 74.093 g/mol. Dividing the given molar mass of Ca(OH)2 with given amount will yield to the moles of the substance.

165 / 74.093 = 2.23 mol Ca(OH)2

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
