At STP what is the volume of 16.34 grams of nitrogen gas?
1 answer:
Answer:
Volume = 13.06 L
Explanation:
We are given: mass of nitrogren gas = 16.34 g
We know: molar mass of nitrogen gas = 28.014 g/mol
: ideal gas law constant = 0.082 L.atm/K.mol
At STP: temperature = 273.15 K
: pressure = 1 atm
We first determine the number of moles of nitrogen gas:
n = m/M
= 16.34/28.014
= 0.58 mol
Using the ideal gas law:

1M KCl will require 25 mL to generate 100 mL of 0.25M KCl.
Molarity of a solution is defined as number of moles of solute present in 1000 mL of the solution.
So molarity is inversely proportional to the volume of the solution.
As solution is diluted. Molarity of the solution decreases.
1M of KCl means 1 mole of KCl in 1000 mL of the solution.
1M KCl is four times as concentrated as 0.25M KCl.
Therefore, to make 100 mL of 0.25M will require of 1M KCl diluted to 100 mL of distilled water.
