Answer:- 324.3 grams.
Solution:- We have been given with 6.0 moles of nitrous acid and asked to calculate it's grams. Moles to grams is a unit conversion and for doing this conversion we multiply the given moles by the molar mass of the compound.
Molar mass is the formula mass and to calculate this the atomic masses of each atom are multiplied by their respective subscripts that is the number of the atom in the compound .
For example, has one nitrogen atom and one oxygen atom. So, the molar mass of this is = atomic mass of N + 2(atomic mass of O)
= 14 + 2(16)
= 14 + 32
= 46 gram per mol
gram per mol is the unit of molar mass. So, the molar mass of is 46 grams per mol.
Let's calculate the molar mass of nitrous acid using the same concept.
molar mass of [ = 1 + 14 + 2(16)
= 1 + 14 + 32
= 47 grams per mol
Now, 6.9 moles of nitrous acid could easily be converted to grams as:
= 324.3 g
Hence, the mass of 6.9 moles of nitrous acid is 324.3 grams.
Solubility and temperatures are directly related. The higher the temperature of the solvent, the higher the solubility of the solute in the solvent.
Dissolving a solute in a solvent is an endothermic process hence providing heat favors the process. Higher temperatures cause the molecules of the solvent to have high kinetic energy hence bombard each other and with that of the solute with high frequency. This then ensures fast diffusion of the solute particles in the solvent.
Answer:
<h3>The answer is 3754.33 g/cm³</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 21.7 kg = 21700 g
volume = 5.78 cm³
We have
We have the final answer as
<h3>3754.33 g/cm³</h3>
