How much mass does 8.46 moles of XeF6 gas have in grams?

2075g of XeF₆ is present in 8.46 moles of XeF₆

Explanation:

Given:

XeF₆ is xenon hexafluoride

number of moles of XeF₆ is 8.46

Mass of XeF₆ present, m = ?

We know,

Molecular weight of XeF₆, M is 245.28 g/mol

and

number of moles, n = mass of XeF₆ present / molecular weight of XeF6

Therefore, 2075g of XeF₆ is present in 8.46 moles of XeF₆

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
