How many grams of barium hydroxide are required to dissolve in 156 g of water to make a 0.247 m solution? Molar mass of Ba(OH)2: 171.346

Explanation:

Moles of Barium hydroxide = 0.156dm³ * (0.247mol/dm³) = 0.0385mol.

Mass of Barium hydroxide = 0.0385mol * (171.346g/mol) = 6.60g.

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.
