The answer needs to be in kg x m/s. According to my professor, the answer is 3.8 x 10^-19 kg x m/s. However, I am not quite sure how he arrived at this answer. Explanation and work shown would be greatly appreciated! Thank you in advance. You are my physics lifesaver!

as momentum means mass * velocity
as we know that the  mass of a proton is 1.67*10^-27 and given velocity of the proton is 0.86
hence putting the values we get 1.4 *10^-27

Please correct your question 
Speed is 0.86c  not 0.86s
 
Given data:
Speed of proton =0.86c =0.86x3x10*8=2.5x10*8
C is speed of light 
Solution :
Mass of proton =1.67x10*-27
Momentum formula=P=mv
P= (1.67x10*-27)x(2.5x10*8)
P= 4.3x10*-19 ,     Answer
