Use your periodic table to get 1 mol. Look up the atomic masses. I'll round the numbers since every periodic table is different.
N = 14
O2 = 2 *16
Total = 30 grams / mol
Therefore 2 mols = twice as much = 60 grams.

Check Explanation
Explanation:
The Heat of reaction for the forward reaction is defined as the amount of heat given off or absorbed while the forward reaction is taking place. Mathematically, the heat of reaction for the forward reaction is given as the heat content/heat of formation/Enthalpies of the reaction's products minus the heat content/heat of formation/Enthalpies of the reaction's reactants.
ΔH°run = H°(products) - H°(reactants)
When the heat of reaction is negative, the reaction is said to be exothermic and when it is positive, the reaction is said to be endothermic.

Answer:
2.9 g/cm³
Explanation:
From the question given above, the following data were obtained:
Mass = 236.376 g
Volume = 81.5 cm³
Density =?
Density can be defined as the mass of a substance per unit volume of the substance. It can be expressed mathematically as:
Density = mass /volume
With the above formula, we can obtain the density of the object as shown below:
Mass = 236.376 g
Volume = 81.5 cm³
Density =?
Density = mass /volume
Density = 236.376 / 81.5
Density = 2.9 g/cm³
Thus, the density of the object is 2.9 g/cm³
Chemical bonds like Ionic bond, covalent bond & dative bond holds them together within a molecule!
Firstly, colligative properties focus on the NUMBER of particles in the ratio of the solute to the solvent. Finally, examples of such are: the decreasing of vapor pressure, the increasing of one's material to its boiling point, the decreasing again of one's material to its freezing point, and osmotic pressure.
