As, mass of one proton,

,i.e., mₚ=1.6726×10¯²⁷kg

To Find:

Mass of 6.022×10²³ p⁺, i.e., 1 mol of protons.

✪★Solution★✪

For finding the mass of Nₐ (Avogrado's number) of protons, multiply the Mass of 1 p⁺ with Nₐ.

Molar mass of proton,

i.e., M.M.ₚ=(1.6726×10¯²⁷×6.022×10²³)kg

⇒M.M.ₚ≈1.0072×10¯³ kg

⇒M.M.ₚ≈1.0072 g

Therefore, the mass of 6.022×10²³protons is approximately equal to 1 gram.
