The neutron mass is 1.675 x 10-27 kg. express the proton mass in ev/c, keeping 4 significant figures b) the mass of the electron is 9.109 x 10-31 kg. express this in ev/c . c) what is the mass of the hydrogen atom in ev/c? ?

Explanation:

given,

mass of neutron = 1.675 × 10⁻²⁷ kg

1 kg =  5.58 × 10³⁵ eV/c²                                        

a) mass of proton = 1.675 × 10⁻²⁷ ×  5.58 × 10³⁵ = 9.34 × 10⁸ eV/c²

b) mass of electron = 9.109 x 10⁻³¹ × 5.58 × 10³⁵ = 5.08 × 10⁵eV/c²

c) mass of hydrogen = 1.675 × 10⁻²⁷  × 5.58 × 10³⁵ = 9.34 × 10⁸ eV/c²

a. carbon monoxide from car exhaust

b.particulate matter, such as soot

c.water vapor from a factory smokestack

d.acid rain

these are the answer choices im on that question right now
