Question

Calculate the mass in grams of 3. 29 x 104 mol of lithium

Help please?

Answer 1

The mass in grams of 3.29 x 10^4 mol of lithium is calculated using the molar mass of lithium (6.94 g/mol), which equals 2.28 x 10^5 grams.

Step-by-step explanation:

To calculate the mass in grams of 3.29 x 104 mol of lithium, we need to use the molar mass of lithium. The molar mass of lithium (Li) is approximately 6.94 g/mol. Therefore, we can use the following calculation:

Mass (g) = number of moles (mol) × molar mass (g/mol)

Substitute the given values into the equation:

Mass (g) = 3.29 x 104 mol × 6.94 g/mol

Mass (g) = 2.28 x 105 grams of lithium.

This is how you would find the mass of lithium when given a large number of moles.

Answer 2

no. of moles =

`\frac{mass \: {g} \: }{ \: molecular \: wight}`

so, mass (g)= no. of moles × molecular wight

Step-by-step explanation:

Li molecular wight equal to 6.941

mass (g)=3.29×104 mol ×6.941 =2374.93g of lithium
