Question

Given that 4NH_3 + 5O_2(g) rightarrow 4NO(g) + 6H_2O(g), if 4.5 moles of NH_3 react with sufficient oxygen, how many moles of H_2O will be formed? A solution contains the label 0.2 M KNO_3. What is the correct interpretation of this concentration? Nitrogen and hydrogen react together to form ammonia according to the equation: N_2(g) + 3H_2O(g) rightarrow 2NH_3(g) Determine how many grams of hydrogen would be required to react with 25.2g of nitrogen. If the theoretical yield for the aspirin synthesis is 54.9g, and 51.3g are actually obtained, the percent yield is: A 4.691g sample of MgCI_2 is dissolved in enough water to give 750.mL of solution. What is the MgCl_2 concentration in this solution? Calcium chloride is used to melt ice and snow on roads and sidewalks and to remove wafer from organic liquids. Calculate the molarity of a solution prepared by diluting 165mL of0.688 M calcium chloride to 925.0mL.

Explanation / Answer

12.

if 4.5 mol of NH3 react --> ratio is 6/4; 1.5

then

4.5*1.5 = 6.75 mol of H2O

mass of H2O = mol*MW

mass = 6.75*18 = 121.5 g of H2O
