What volume (in liters, at 253 K and 6.54 atm) of chlorine gas is required to react with 7.89 g of P? 2P(s) + 5Cl2(g) → 5PCl5(s)

7.89 grams of phosphorus reacts with 45.15 grams of chlorine

Explanation:

For reacting with 2 mole of P react with 5 mole of Cl2 gas

Molecular weight of phosphorus = 30.97

Molecular weight of 2 mole of phosphorus = 2 * 30.97 = 61.94 grams

Molecular weight of Chlorine molecule = 70.9 grams

Weight of 5 moles of Chlorine molecule = 5 * 70.9 grams = 354.5 grams

61.94 grams of phosphorus reacts with 354.5 grams of chlorine

7.89 grams of phosphorus reacts with 354.5/61.94 * 7.89  grams of chlorine

7.89 grams of phosphorus reacts with 45.15 grams of chlorine

stupid i wont let you get a chance

explanation:

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.
