Belen Hansen · Answer 1

Same as 2.50 moles of anything. multiply number of moles by avagadro’s numberino:

(2.50) 6.022e23=1.51e24

Elianna Fischer · Answer 2

1.5*1024 molecules.

Explanation:

You can calculate the number of molecules from moles by using Avogadro's constant, 6.02*1023molecules/mol.

For every 1 mol, there are 6.02*1023 molecules.

Simply multiply

2.5 mol*6.02*10231 mol=1.5*1024 molecules
