mass of NaNO₃ : 81.515 g
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products
Reaction
HNO₃ + NaOH ⇒ NaNO₃ + H₂O
MW HNO₃ = 63 g/mol
MW NaNO₃ =85 g/mol
475 mL of 12% nitric acid (HNO₃)(density 1.06 g / mL)
Molarity HNO₃ :
[tex]\tt M=\dfrac{\%\times \rho\times 10}{MW}\\\\M=\dfrac{12\times 1.06\times 10}{63}=2.019[/tex]
[tex]\tt mol=M\times V\\\\mol=2.019\times 0.475~L=0.959[/tex]
mol HNO₃ : mol NaNO₃ = 1 : 1 = 0.959
[tex]\tt mass=mol\times MW=0.959 \times 85=81.515~g[/tex]
