The answer is B) Accurate. Authentic in this case basically means Accurate. They try to create accurate models. Plus, it is the only one that really actually makes sense.

V=1cm³
ms = 0,904g * 0,26 = 0,23504g
M=17,04g/mol
n = m / M = 0,23504g / 17,04g/mol ≈ 0,0138mol
mso = 0,904g - 0,23504g = 0,66896g
C = 0,0138mol / 0,66896g = 0,021 mol/0,001kg=21 mol/kg
2.10
The 0 after 1 is not significant and does not affect the value of the number; therefore, when the number will be rounded to two significant figures, it will become 2.1, so it will be the same.
<h3><u>Answer;</u></h3>
= 1.615 moles
<h3><u>Explanation</u>;</h3>
The molar mass of NO2
= 46.01 g/mol
The mass of NO2 given is 74.3 g
Number moles = mass/ molar mass
= 74.3 g/ 46.01 g/mol
= 1.615 moles
