Answer : The molar mass of silver nitrate is, 169.87 g
Explanation :
Molar mass : It is defined as mass of 1 mole of a substance.
Given:
Molar mass of Sliver (Ag) = 107.8682 g
Molar mass of nitrogen (N) = 14.0067 g
Molar mass of oxygen (O) = 15.9994 g
Now we have to calculate the molar mass of silver nitrate
Molar mass of silver nitrate = Molar mass of Sliver (Ag) + Molar mass of nitrogen (N) + (3 × Molar mass of oxygen (O))
Molar mass of silver nitrate = 107.8682 g + 14.0067 g + 3(15.9994 g)
Molar mass of silver nitrate = 169.87 g
Therefore, the molar mass of silver nitrate is, 169.87 g

Answer:
The equilibrium concentration of CH₃OH is 0.28 M
Explanation:
For the reaction: CO (g) + 2H₂(g) ↔ CH₃OH(g)
The equilibrium constant (Keq) is given for the following expresion:
Keq= =14.5
Where (CH3OH), (CO) and (H2) are the molar concentrations of each product or reactant.
We have:
(CH3OH)= ?
(CO)= 0.15 M
(H2)= 0.36 M
So, we only have to replace the concentrations in the equilibrium constant expression to obtain the missing concentration we need:
14.5=
14.5 x (0.15 M) x = (CH₃OH)
0.2818 M = (CH₃OH)
Answer: Aluminum,
Explanation:
Density is defined as the mass contained per unit volume. It is characteristic of a substance.
Given : Mass of object = 8.44 grams
Volume of object=
Putting in the values we get:
Thus density of the object will be which matches that of aluminium.
