If 15.0 of is dissolved in enough water to form 270 of solution, what is the molarity of the solution?
What is the oxidation state of an individual sulfur atom in ?
What is the oxidation state of an individual nitrogen atom in ?
To find the molarity of a solution, you need to divide the number of moles of solute by the volume of the solution in liters.
1. First, you need to convert the given mass of solute into moles using the formula: moles = mass / molar mass.
Given that 15.0 g of solute is dissolved, you'll need to know the molar mass of the solute compound.
2. Once you have the moles of solute, you can calculate the molarity by dividing the moles by the volume of the solution in liters.
Given that the volume of the solution is 270 mL, you'll need to convert it to liters by dividing by 1000.
Therefore, to find the molarity of the solution:
- Calculate the moles of solute using the molar mass.
- Convert the volume of the solution from mL to L.
- Divide the moles of solute by the volume of the solution to get the molarity.
To determine the oxidation state of an individual sulfur atom in a compound, you need to take into account its electronegativity and its number of valence electrons.
- Firstly, determine the formula of the compound.
- Identify the oxidation states of any other atoms in the compound.
- Assign an oxidation state to sulfur based on the known oxidation states of the other atoms and the overall charge of the compound (if applicable).
For the oxidation state of an individual nitrogen atom in a compound, you'll need to apply a similar process:
- Determine the formula of the compound.
- Identify the oxidation states of any other atoms in the compound.
- Assign an oxidation state to nitrogen based on the known oxidation states of the other atoms and the overall charge of the compound (if applicable).
Remember that oxidation states are hypothetical charges assigned to atoms for the purpose of chemical reactions. Factors like electronegativity, valence electrons, and the compound's overall charge can help determine the oxidation states.
