what mass of na₂so₄ is required to generate 12.0 g baso₄? molar mass baso₄ = 233.39 g/mol molar mass na₂so₄…

Explanation:

Step1: Calculate moles of ( BaSO_4 )

Moles = mass / molar mass. So, moles of ( BaSO_4 = \frac{12.0\ g}{233.39\ g/mol} ) ( \approx 0.05142\ mol )

Step2: Determine moles of ( Na_2SO_4 )

From the balanced equation, the mole ratio of ( Na_2SO_4 ) to ( BaSO_4 ) is 1:1. So moles of ( Na_2SO_4 ) = moles of ( BaSO_4 = 0.05142\ mol )

Step3: Calculate mass of ( Na_2SO_4 )

Mass = moles × molar mass. So mass of ( Na_2SO_4 = 0.05142\ mol × 142.04\ g/mol ) ( \approx 7.30\ g )

Answer:

( 7.30) (or more precise value based on calculation steps, e.g., if calculated with more precision: ( \frac{12.0}{233.39}×142.04 \approx 7.30))
