how many electrons can be held in the energy level n = 4?

ANSWER: 32

Explanation: i think is 32 because s have 1 orbital p has 3 d has 5 and f has 7 add them all up we got 16 orbitals  each orbitals can contain 2 electrons

16 times 2 we got 32 electrons.

not 100%percent sure because some people told me the answer is 16.

in the given question, the partial pressure is calculated by using the ideal gas equation, that is, pv = nrt

here, p is pressure, v is volume = 25 l, n is number of moles = 0.0104 moles, r is gas constant = -0.0821 l.atm / mol.k

t is temperature = 273 k

p = nrt / v

p = (0.0104 mol × 0.0821 l.atm / mol.k × 273 k) / 25 l

= 0.0093 atm

nacl is added to the aqueous of what? ? in order to get a proper answer you have to specify the exact composition of the aqueous solution.
