doing a lab experiment and i need to prepare sodium-calcium acetate and potasium-calcium acetate glasses.

the 1st step says: weigh out about 0.025moles of each precursor.
i'm not entirely sure what the precursors are.
anyway i know mass=mol/atomic mass.
i'm not sure the formula though to calculate the atomic mass.
tried searching for it but no avail. any help?

[Borek]

mass=mol/atomic mass

Where did you get this formula from?

[newbie!]

haha sorry it's mass=mol x atomic mass.

[Borek]

If it would say molar mass, would it be easier?

[newbie!]

do i just need to multiply 0.025 by each of the components molar mass. (molar mass = atomic mass=gfm right?)

each component being sodium , calcium and acetate?

each component being sodium , calcium and acetate?

No idea what you mean.
