Calculate the molarity of a solution prepared by dissolving 195 g of sodium chloride (NaCl) in enough water to make 2.8 liters of solution.

molarity of a solution = 1.192 M

Explanation:

∴ mass NaCl = 195 g

∴ molar mass NaCl = 58.44 g/mol

⇒ moles NaCl = (195 g)*(mol/58.44 g) = 3.34 mol

∴ Volumen solution = 2.8 L

⇒ Molarity NaCl solution = (3.34 mol)/(2.8 L) = 1.192 M

yes, water is wet, just as it makes other things wet, it is wet itself, kinda like ice, when ice is in water, the ice makes water cold, and ice is cold, therefore with that example, water is wet

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.
