Answer
a. 1.50 L of solution
b. 10.0 L of solution
c. 62.5 mL of solution
Work Step by Step
a.
1. Find the conversion factor:
- 2.00 M $KBr$ solution: $$2.00 \space moles \space KBr = 1 \space L \space solution$$
2. Calculate the volume in L:
$$3.00 \space moles \space KBr \times \frac{1 \space L \space solution}{2.00 \space moles \space KBr} = 1.50 \space L \space of \space solution$$
b.
1. Find the conversion factors
- 1.50 M $NaCl$ solution: $$1.50 \space moles \space NaCl = 1 \space L \space solution$$
2. Calculate the volume in L:
$$15.0 \space moles \space NaCl \times \frac{1 \space L \space solution}{1.50 \space moles \space NaCl} = 10.0 \space L \space of \space solution$$
c.
1. Find the conversion factors
- 0.800 M $Ca(NO_3)_2$ solution: $$0.800 \space mole \space Ca(NO_3)_2 = 1 \space L \space solution$$
- 1 L = 1000 mL
2. Calculate the volume in mL:
$$0.0500 \space mole \space Ca(NO_3)_2 \times \frac{1 \space L \space solution}{0.800 \space mole \space Ca(NO_3)_2} \times \frac{1000 \space mL}{1 \space L}= 62.5 \space mL \space of \space solution$$
