The atomic mass of an atom of nitrogen is approximately 14 amu, and the atomic mass of an atom of oxygen is approximately 16 amu. To produce nitric oxide, NO, 16 g of oxygen
combine with 14 g of nitrogen. To produce nitrogen dioxide, NO2, 32 g of oxygen combine
with 14 g of nitrogen. The ratio of the mass of oxygen in NO2 to the mass of oxygen in NO is
a. 1:1 or 1.0
b. 2:1 or 2.0
c. 1:2 or 0.50
d.
8:3 or 2.7

Need asap

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

u i forgot the answer?

it's c. elements are placed in rows based on how may valencies electrons have.

your answer is c) plasma
