1 mole ----------- 6.02x10²³ molecules
? moles ---------- 3.4x10²³ molecules
(3.4x10²³) x 1 / 6.02x10²³ =
3.4x10²³ / 6.02x10²³ => 0.564 moles of H2SO4
Answer: The density of silver metal will be ![10.50g/ml[\tex]Explanation:Density is defined as the mass contained per unit volume.[tex]Density=\frac{mass}{Volume}](https://tex.z-dn.net/?f=10.50g%2Fml%5B%5Ctex%5D%3C%2Fp%3E%3Cp%3EExplanation%3A%3C%2Fp%3E%3Cp%3EDensity%20is%20defined%20as%20the%20mass%20contained%20per%20unit%20volume.%3C%2Fp%3E%3Cp%3E%5Btex%5DDensity%3D%5Cfrac%7Bmass%7D%7BVolume%7D)
Given : Mass of silver = 194.3 grams
Volume of silver= volume of water displaced= ![260.5-242.0=18.5mltex]Putting in the values we get:[tex]Density=\frac{194.3g}{18.5ml}=10.50g/ml/tex]Thus density of silver metal will be [tex]10.50g/ml](https://tex.z-dn.net/?f=260.5-242.0%3D18.5mltex%5D%3C%2Fp%3E%3Cp%3EPutting%20in%20the%20values%20we%20get%3A%3C%2Fp%3E%3Cp%3E%5Btex%5DDensity%3D%5Cfrac%7B194.3g%7D%7B18.5ml%7D%3D10.50g%2Fml%2Ftex%5D%3C%2Fp%3E%3Cp%3EThus%20density%20of%20silver%20metal%20will%20be%20%5Btex%5D10.50g%2Fml)
Answer:
The pH of the final solution is 0.16 .
Explanation:
The pH of the solution is defined as negative logarithm of hydrogen ion concentration in a solution.
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
Concentration of HCl = 0.16 M
HCl is a string acid .1 molar of HCl gives 1 molar of of hydrogen ions.
![[H^+]=0.16 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.16%20M)
Concentration of 
= 0.52 M
Nitric is a string acid .1 molar of nitric acid gives 1 molar of of hydrogen ions.
![[H^+]'=0.52 M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%27%3D0.52%20M)
Total hydrogen ion concentration:
![[H^+]''=[H^+]+[H^+]'](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%27%27%3D%5BH%5E%2B%5D%2B%5BH%5E%2B%5D%27)
=0.16 M+0.52 M=0.68 M
The pH of the solution:
![\pH=-\log[H^+]''=-\log[0.68 M]](https://tex.z-dn.net/?f=%5CpH%3D-%5Clog%5BH%5E%2B%5D%27%27%3D-%5Clog%5B0.68%20M%5D)
pH = 0.16
The pH of the final solution is 0.16 .

Answer:
Option 3. Specific heat capacity of the liquid
Explanation:
Let's think, the states for the substance.
In -10, substance turns from solid state to liquid, so at 2°C , state is liquid.
We have to take from liquid state at 2°C to 155°C, which is the boiling point.
As the substance doesn't change its state, we only have to apply the specific heat capacity of the liquid.
1. specific heat capacity of the solid → This is used, when the substance is solid.
2. Heat of fusion → Only used when you turn from liquid to solid
4. Heat of vaporization → Used when the substance changes its state from liquid to gas
5. specific heat capacity of the gas → Used when the substance is a gas.
