Answer:
1.41 moles H2O2(with sig figs)
Explanation:
okay so what is the molar mass of H2O2= (1.008 g/mol)2+(16.00g/mol)2= (2.016+ 32.00) g/ mol
= 34. 02 g/mol
48.0g H2O2* 1 mol H2O2/ 34.02 g H2O2= 1.41 mol H2O2

i is vant Hoff factor
For NaCl vant Hoff factor is 2( Actually 1.9)

Answer:
A converter to convert from dc to ac
Explanation:
*** Remember ***<u /> Dehydration synthesis is when two molecules are joined together, by removing a water molecule. Also a key thing to remember is that <em>dehydration</em><u /> can be remembered as "losing water".
During dehydration synthesis, a <u> water </u><u /> molecule is produced.
I hope this helps! :D
