Understand that the problem asks for the approximate mass of a proton, which is a fundamental particle in chemistry and physics.
Recall that the mass of a proton is typically expressed in kilograms using scientific notation because it is extremely small.
Recognize that the mass of a proton is about 1.67 times 10 to the power of -27 kilograms, which is a standard accepted value in chemistry.
Compare the given options by looking at both the coefficient (the number before the multiplication sign) and the exponent (the power of 10) to see which one matches the known value.
Select the option that has a coefficient close to 1.67 and an exponent of -27, since this correctly represents the approximate mass of a proton.
