Hey there!
1 mole has 6.022 x 10²³ atoms.
Multiply that by 3.2 because we have 3.2 moles.
3.2 x 6.022 x 10²³
1.9 x 10²⁴
There are 1.9 x 10²⁴ atoms in 3.2 moles of chromium.
Hope this helps!
Answer:
A. 0.228
Explanation:
Partial pressure as name suggests is partial pressures that add up to a final (total) pressure.
Here total pressure is 1.348 atm.
He + Ne + N2 = 1.348
0. 124 + 0.996 + N2 = 1.348
N2 = 0.228
