What number of moles of nitrogen are present in 5.00g of Calcium Nitrate Ca(NO3)2?

Expert Solution

masss of Calcium Nitrate = Ca(NO3)2 = 5.00 g

molar mass of Calcium Nitrate = Ca(NO3)2 = 164.09 g/mole

number of moles of Nitrogen present in 164.09 grams of Ca(NO3)2 = 2 moles of Nitrogen[ according to the molecular formula]

number of moles of Nitrogen presetn in 5.00 grams of Ca(NO3)2 = ?

= 2x5.00/164.09

= 0.0609 moles

number of moles of Nitrogen present in 5.00 grams of Ca(NO3)2 = 0.0609 moles.

A solid hydrate of Ca(NO3)2 is to be analyzed (Ca(NO3)2 •XH2O). A sample of the hydrate is weighed in a clean, dry and covered crucible. When empty, the crucible and cover are heated to a constant weight of 30.2016 g. The mass of the crucible and sample is 33.2255 g. The crucible with sample is heated (to drive off the water of hydration) to a final constant weight of 32.2995 g Table 1: Mass Data for the Analysis of a...

Combustion produces oxides of nitrogen and oxides of sulfur, which can be oxidized to nitrate (NO3-) and sulfate (SO42-) respectively in the atmosphere: the nitrate and sulfate subsequently may be deposited by both wet and dry processes. Cite and explain specific regional or global-scale problems, or potential problems, that may be exacerbated by increased levels of nitrate and sulfate deposition in precipitation.
