How many li atoms are contained in 97.9 g of li

The number of atoms in given mass of lithium element is

Explanation:

To calculate the number of moles, we use the equation:

Mass of lithium = 97.9 g

Molar mass of lithium = 6.94 g/mol

Putting values in above equation, we get:

According to mole concept:

1 mole of an element contains number of atoms

So, 14.12 moles of lithium will contain = number of atoms.

Hence, the number of atoms in given mass of lithium element is

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
