Answer:
C. 4 × 6.02 × 10²³ potassium atoms.
Explanation:
In 1.00 mol of potassium zirconium sulfate trihydrate, K₄Zr(SO₄)₄.3 H₂O, there are
A . 3 × 6.02 × 10²³ hydrogen atoms. NO. There are 3 × 2 moles of hydrogen atoms = 6 moles of hydrogen atoms = 6 × 6.02 x 10²³ hydrogen atoms
B. 6.02 × 10²³ sulfur atoms. NO. There are 4 moles of sulfur atoms = 4 × 6.02 × 10²³ sulfur atoms
C. 4 × 6.02 × 10²³ potassium atoms. YES. There are 4 moles of potassium atoms = 4 × 6.02 × 10²³ potassium atoms
D . 4 moles of oxygen atoms. NO. There are 4 × 4 moles of oxygen atoms = 16 moles of oxygen atoms
E . 4 moles of zirconium atoms NO. There is 1 mole of zirconium atoms
