26g --- 1 mol
56g --- X
X= 56/26 = 2,154 mol
959 ml = 959cm³ = 0,959dm³
C = n/V
C = 2,154/0,959
C = 2,246 mol/dm³
THE MOLAR MASS OF FLUORINE IS 35G/MOL
Answer: C: experimentation is the best way to obtain knowledge
Explanation: When experimenting you will learn new things and better understand things from it.
The ph would most likely be 7
hope this helps
Mass of water = 80 x 18
= 1440 grams
Specific heat of water = 4.186 J/gK
Heat absorbed from water = mCpΔT
= 1440 x 4.186 x (21.6 - 18.1)
= 21.1 kJ
Moles of NH₄NO₃ = 3.53 / (14 + 4 + 14 + 16 x 3)
= 0.044 mol
Heat of solution = 21.1/0.044 kJ/mol
= 480 kJ/mol
