Question

Which would have more mass: a mole of sodium or a mole of copper? How do you know?

Answer 1

copper

Step-by-step explanation:

so for this you can work out the mass for both and compare

so mass = moles × mr

so mass of sodium = 1 × 23= 23 g

and mass of copper = 1 × 63.5= 63.5 g

so copper have more mass :)
