Consider an experimental run at 273 K where the initial number of moles (n1) is actually 1.00 mol, and the final number of moles (n2) is 2.00 mol. Use the simulation to find the volume (V1) of 1.00 mol of helium at 273 K, and calculate the final volume (V2). Express the volume to three significant figures, and include the appropriate units.

The volume of 1.00 mol of helium at 273 K is 22.4 L and the final volume is 44.8 L.

Explanation:

Given: = 273 K,   = 1.00 mol

= 273 K,         = 2.00 mol

At the standard pressure, 1 atm the value of and is calculated as follows.

Similarly,

Thus, we can conclude that the volume of 1.00 mol of helium at 273 K is 22.4 L and the final volume is 44.8 L.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
