The present atomic weight scale is based on

What is the molar mass of the compound represented by the following structural formula?

Calculate the molecular mass of glucose $[C_{6}H_{12}O_{6}]$ molecule. (in $u$)

When a metal oxide is heated in a stream of hydrogen,reduction occurs. After reduction,$3.15 \, g$ of the oxide yields $1.05 \, g$ of the metal. What can we conclude about the metal?

Which symbol replaced the unit of atomic mass,$amu$?

Atoms consist of protons,neutrons,and electrons. If the mass of neutrons were made half and the mass of electrons were made two times their actual masses,then the atomic mass of $_6C^{12}$ would:
