What is the mass of 0.100 mole of neon? (watch sf’s) 2.018 g 20.18 g 2.02 g 2 g

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!

the answer is true.

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
