Question 12 (1 point) The atomic number tells you how many protons are in the nucleus and how many electrons are orbiting the nucleus. To determine the number
of neutrons in the nucleus, the atomic number needs to be subtracted from the mass number.
O True
O False

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

the answer is a for sure mark brainliest i had got this right on usatestprep
