1 Molar solution contains

Options

A. 1000g of solute
B. 1000g of solvent
C. 1 litre of solvent
D. 1 litre of solution

Answer

To determine what a 1 Molar (1 M) solution contains, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Molarity**: Molarity (M) is defined as the number of moles of solute per liter of solution. Therefore, a 1 M solution contains 1 mole of solute in every liter of solution.

2. **Volume of Solution**: The question specifies a 1 M solution, which means we are considering a total volume of 1 liter (1000 mL) of the solution.

3. **Calculating Moles of Solute**: Since we have a 1 M solution, this means:
\[ \text{Moles of solute} = 1 \text{ mole} \]
in 1 liter of solution.

4. **Conclusion**: Therefore, a 1 Molar solution contains 1 mole of solute dissolved in 1 liter (1000 mL) of solution.

### Final Answer:
A 1 Molar solution contains 1 mole of solute in 1 liter (1000 mL) of solution.
