∙ 14y ago1 mol of NaCl is 58.5 grams (Ar of Na is 23, and Ar of Cl is 35.5). Now we set up an equation
1 mol : x = 58.5 g : 2.4 g
x = 0.0410 mol
So, 2.4 grams of NaCl has 0.0410 moles of NaCl.?

∙ 13y agoThe atomic weight of Na is 23.0 g/mol
To convert moles to grams:
grams Na = 2.04 mol Na23.0 g = 46.9 g Na1 mol
Multiply by grams per mole. Moles cancel out.

∙ 13y agoThe conversion factor between atoms and moles is Avogadro's number: 6.02 x 1023 "things" / mol
To convert atoms to moles:
moles Na= 2.61E+24 atoms Na1 mol Na= 4.34 mol Na6.02 x 1023 atoms Na
Multiply by moles per atom. Atoms cancel out.

∙ 13y ago1.538 X 10^24 atoms of sodium (1 mole Na/6.022 X 10^23)
= 2.554 moles of sodium

∙ 12y ago2.06*1024 (atoms) / 6.02*1023 (particles/mole) = 3.42 mole atoms of any mono-atomic element (eg. Mg).

∙ 9y agoEach mole has 6,022 141 29.10ex.23 atoms (N - number of Avogadro).
N x 2,8 is 16,861 995 6.10ex.23 sodium atoms.
