A proton has mas 1.67x10 -27 kg and diameter 8.2 x 10 -16 m. Find specific gravity.

Thank you for posting your question to the Ask Me Help Desk.

Recall that specific gravity of a substance is the density of the substance compared to the density of water.

Do you remember the formula for density?

Do you have the information required to determine the values needed for the formula?

This should be sufficient information to help you get started.

Let me know what you come up with.
