Question

The molar mass of LiF is 25.94 g/mol. What mass of LiF would 1.33 x

10^24 molecules? Report to the hundredths.

Answer 1

The mass of LiF for 1.33 x 10^24 molecules is 57.13 g.

Step-by-step explanation:

The molar mass of LiF is 25.94 g/mol. To find the mass of LiF for 1.33 x 10^24 molecules, we need to convert the given quantity of molecules to moles using Avogadro's number (6.022 x 10^23 molecules/mol).

Then, we can use the molar mass to calculate the mass of LiF.

First, convert the molecules to moles:

1.33 x 10^24 molecules ÷ (6.022 x 10^23 molecules/mol) = 2.207 mol

Next, calculate the mass of LiF:

2.207 mol x 25.94 g/mol = 57.13 g

Therefore, the mass of LiF for 1.33 x 10^24 molecules is 57.13 g.
