      3rd Standard- Mass per mole of any substance = molar mass

    1. I'm not sure what Standard means. I'm having trouble understanding and finding what the standard of all the 7 fundamentals are.

    2. Also, why is the king of England's foot wrong for the standard for length? I understand that if they change the length whenever a new king came into power, then it wouldn't be standard, but I thought they just kept the length based off of one king's foot?
