How many moles in Co are there in 6 billion Co atoms

1 answer:

3 0

Hello there!

 Use Avogadro's number, 1 mol = 6.02 x 10^23 atoms.
Convert atoms to moles and you get:

9.97x10^(-15) moles Co

Hope This Helps You!
Good Luck :)

Grams of sodium 9.5g in NaCl

Kitty [74]

Answer:

3.68 grams.

Explanation:

First we convert 9.5 g of NaCl into moles of NaCl, using its molar mass:

9.5 g ÷ 58.44 g/mol = 0.16 mol NaCl

In 0.16 moles of NaCl there are 0.16 moles of sodium as well.

We now convert 0.16 moles of sodium into grams, using sodium's molar mass:

0.16 mol * 23 g/mol = 3.68 g
