0.20 L of HNO3 is titrated to equivalence using 0.12 L of 0.2 M NaOH. What is the concentration of the HNO3?

AleksandrR [38]

$M_{A}V_{A}=M_{B}V_{B}\\(0.20)(M_{A})=(0.12)(0.2)\\M_{A}=\frac{(0.12)(0.2)}{(0.20)}=\boxed{0.12 \text{ M}}$

Na2SO4 is dissolved in water to make 450mL of a 0.2250 M solution. What is the molar mass of Na2SO4?

Alisiya [41]

Answer:

mass Na2SO4 = 14.3816 g

Explanation:

sln Na2SO4:

∴ V = 450 mL

∴ <em>C </em>=<em> </em>0.2250 mol/L

∴ Mw ≡ 142.04 g/mol..... from literature

⇒ mol Na2SO4 = (0.2250 mol/L)(0.450 L) = 0.10125 mol

⇒ mass Na2SO4 = (0.10125 mol)(142.04 g/mol) = 14.3816 g
