How many particles can be stored in a 4.0 L container at room temperature (23 C) and standard atmospheric pressure (101.3 kPa)?
1 answer:
0.16 moles
<h3>Further explanation</h3>There are 2 conditions that are usually used as a reference in chemical calculations (mainly for determining the volume per mole of gas or the molar volume), namely:
- 1. Standard Conditions
stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.
- 2 Room Condition
stated by RTP (Room Temperature and Pressure). Vm in this condition = 24.4 liters / mol
so for 4 L :

Explanation:
The standard cell potential at 298 K is given by;
E°cathode - E°anode
Hence;
E°cell = 0.34 V - (-0.76 V)
E°cell = 0.34 V + 0.76 V
E°cell = 1.1 V
To reduce Zn^2+ to Zn then Zn must be the cathode, hence;
E°cell = (-0.76 V) - 0.34 V
E°cell = -1.1 V
