What is the mass of 0.100 mole of neon? (Watch sf’s) 2.018 g 20.18 g 2.02 g 2 g
makkiz [27]

Answer:

The mass of 0.100 mole of neon is 2.018 grams.

Explanation:

As we know the formula to find mass:

                           Number of moles         =  Mass/ Molar mass

                                        0.100                = Mass/ 20.17

                                        0.100 x 20.17   = Mass

                                                        Mass=2.018 grams.

Hope it helps!
