DESCRIPTION

Mass to mass used when we are carrying out a reaction in the lab start with given use molar mass to convert to moles use mole to mole ratio to convert to moles of the other substance use molar mass to get the mass of the new substance Ammonium nitrate (NH 4 NO 3 ), an important fertilizer, produces N 2 O gas and H 2 O when it decomposes. Determine the mass of water produced from the decomposition of 25.0 g of solid ammonium nitrate.

PracticeIf you begin with 1.25 mole of TiO2, what mass of Cl2 is needed?

TiO2 + C +2Cl2 TiCl4 +CO2

One in a series of reactions that inflate air bags in automobiles is the decomposition of sodium azide . Determine the mass of N2 produced if 100.0 g NaN3 is decomposed.

2NaN3 2Na + 3 N2
