Answer:
Radiation is being released from the reactor.
Explanation:
( A P E X )
Molar concentration is the number of Na₂SO₄ moles that are dissolved in 1 L of solution.
when 625 mL is added to 344 mL of Na₂SO₄, then the number of moles that are dissolved in 344 mL remains constant but volume increases. Therefore concentration now decreases.
Molar concentration of Na₂SO₄ is 1.675 M
the number of Na₂SO₄ moles in 1000 mL - 1.675 mol
then number of Na₂SO₄ moles in 344 mL - 1.675 mol / 1000 x 344 = 0.5762 mol
the new volume - 344 mL + 625 mL = 969 mL
concentration = number of moles / volume
therefore new concentration = 0.5762 mol / 0.969 L = 0.595 mol/L
new concentration of Na₂SO₄ is 0.595 M
oxygen added to the copper is 3.300 grams.
<span>89.920 - 83.620 = 3.300 g oxygen </span>
<span>which is 0.2063 moles of oxygen. </span>
<span>3.300 g O x (1 mol O / 16.00 g O) = 0.20625 mol </span>
