Answer: 1. The solvent in a mixture of gases is generally considered to be the substance in greater amount. 2. The solid dissolved in a solution is known as the solute. 3. Solid solutions are called alloys.
Explanation:
A binary solution is made up of two components ,called as solute and another as solvent.
A solute is defined as the component which is present in smaller proportion. It can be in solid, liquid or gaseous phase. A solvent is defined as the component which is present in larger proportion in a solution. It can be in solid, liquid or gaseous phase.
Usually in liquid solutions , solid acts as solute and liquid acts as solvent. For example: In salt solution, salt is the solute and water is the solvent.
Solid solutions contains solid as solute and solid as solvent. These are called as alloys. For example : In brass, zinc is the solute and copper is the solvent.
If the object is less dense then the object will float
Answer:
18.81 g
Explanation:
We are given;
- Volume of Barium nitrate as 21.29 mL or 0.02129 L
- Molarity of Barium nitrate as 3.38 M
We are required to determine the mass of Barium nitrate
Step 1: Determine the number of moles of Barium nitrate
Number of moles = Molarity × Volume
= 3.38 M × 0.02129 L
= 0.07196 moles
Step 2: Determine the mass of Barium nitrate
We know that;
Mass = Number of moles × Molar mass
Molar mass of Barium Nitrate is 261.337 g/mol
Therefore;
Mass of barium nitrate = 0.07196 moles × 261.337 g/mol
= 18.8058 g
= 18.81 g
Thus, the mass of barium nitrate dissolved is 18.81 g
