1. 0.150 g of sulfamic acid is used in this experiment, how many grams of NaNO2 should be used to ensure that all of the sulfamic acid reacts? How many moles of nitrogen gas will be produced? Answers: 0.107 g, 1.54 x 10 mole 4. In an experiment, N2 gas is produced and collected over water in an inverted buret as shown in Figure 1. Lab temperature was 20.0°C and barometric pressure was 700.0 mm Hg. The difference in the...

Station 2: Calculations with the Ideal Gas Law A Station Letter: A student reacted a strip of magnesium metal with 4.00 mL of 4.0 M hydrochloric acid and collected the hydrogen gas produced using the experimental setup you see at the station. Unfortunately, the student forgot to record the mass of the metal before they reacted it with acid. Determine the mass of the magnesium metal the student used in the experiment. For this experiment assume the pressure of the...

Calculate the amount of gas produced when collected by water displacement. Aluminum reacts with aqueous sodium hydroxide to produce hydrogen gas: 2Al(s) + 2NaOH(aq) + 6H2O(1) 2NaAl(OH)4(aq) + 3H2(g) In one experiment, a sample of Al reacts and the gas produced is collected by water displacement. The gas sample has a temperature of 23.00 °C, a volume of 860.0 mL, and a pressure of 747.0 mm Hg. Calculate the amount (in moles) of hydrogen gas produced in the reaction. The...
