Answer:
2.25 M <========= I do not see this in your selection of answers !
Explanation:
Mole weight of Li F
( from periodic table ) = 6.94 + 18.998 = 25.938 gm/mole
56 gm / ( 25.938 gm /mole) = 2.15899 moles
2.15899 mole / (.959) L = 2.25 M
Answer:
1 mole
Explanation:
The mole (mol) is the amount of a substance that contains the same number of entities as there are atoms in exactly 12 g of carbon-12. One mole (1 mol) contains 6.022x1023 entities (to four significant figures).
