In order to measure 0.733 moles of KBr from a 3.00 M solution, the chemist needs 244 mL of solution.
<h3>What is molarity?</h3>
Molarity (M) is a unit of concentration of solutions, and it is defined as the moles of a solute per liters of a solution.
- Step 1: Calculate the liters of solution required.
A chemist has a 3.00 M KBr solution and wants to measure 0.733 moles of KBr. The required volume is:
0.733 mol × (1 L/3.00 mol) = 0.244 L
- Step 2: Convert 0.244 L to mL.
We will use the conversion factor 1 L = 1000 mL.
0.244 L × (1000 mL/1 L) = 244 mL
In order to measure 0.733 moles of KBr from a 3.00 M solution, the chemist needs 244 mL of solution.

The number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.
<h3>What are limiting reactants?</h3>
Limiting reactants are those reactants which determine the amount of product that can be formed since they get used up in a reaction.
In the making of sandwiches from bread and cheese, the limiting reactant is the material that is used up.
The formula for making a sandwich is given below;
2 pieces of bread + 1 slice of cheese = 1 sandwich
6 pieces of bread can make 3 sandwiches
4 slices of cheese can make 4 sandwiches
Thus, bread is the limiting reactant.
Therefore, the number of sandwiches that can made with 6 pieces of bread and 4 slices of cheese is 3 sandwiches.
