The density of a proton is approximately 4.0 x 1014 g/cm. If the mass of the proton is 1.7 x 10.24 g, calculate its volume. V=12 g 1.7x1024 4.0104 (4.25x 10-39 cm 4 b. Using the volume of a sphere equation, determine the radius of the proton in centimeters (cm). The volume of a sphere: V=. (= 3.14159) 14/TTP (4.25x 10-39) 3 (3.41593 4 c. Convert this answer to nanometers (nm)
