Express your answer to two significant figures and include the appropriate units.

Answer 1

1. 40/42 x 0.375=2,51952633 L of NaF.

2. 40/183 x 0.375 = 0,58287796 L of CdCl2.

3. 10/138 x 0.497 = 0,14580235 L of K2CO3.

4. 10/306.5 x 0.497=0,0656467352 L of Fe(ClO3)3.

5. 0.07 x 6 /0.4 = 1,05 M. CH3COOH.

6. 6 x 0.4 /23 = 0,104347826 L of HNO3.
