Ammonium nitrate
Ammonium = NH4+
Nitrate = NO3-
Here, the solution can't be separated by filtration means, the solute is dissolved at greater extent with solvent. The category would be: Colloid
In short, Your Answer would be: "Colloid"
Hope this helps!
Answer:
Molarity of dextrose = 0.03 mol / L
Explanation:
Given data
mass of dextrose = 5 g
Concentration (Molarity) = ?
Solution
as mass is given so we find out number of moles
<em>Moles = mass / molar mass</em>
Molar mass of dextrose = 180.156 g/mol
Moles = 5 g / 180.156 g/mol
Moles = 0.03 moles
Now we find out molarity
<em>Molarity = moles of solute / Litres of solution</em>
As volume is not given so we suppose it as 1 L
Molarity of dextrose = 0.03 mol / 1 L
Molarity of dextrose = 0.03 mol / L
Answer:
Average acceleration = - 2 m/s^2
Explanation: Have a nice day
The mass of Au is 19.7 g
The chemical reaction may be
Au₂S₃ + 3H₂ → 2Au + 3H₂S
1 mole of Au₂S₃ gives 2 mole of Au
Then 0.0500 mol of Au₂S₃ gives
0.0500 × 2 / 1
= 0.10 moles.
To find mass
Mass = moles × molar mass
Moles = 0.10.
Molar mass = 197 g
Mass = 0.10 × 197
= 19.7 g
Hence the mass of Au produces is 19.7 g
