The answer is: " 480 mL of [2.50 M K₂SO₄] solution."
____________
Explanation:
Given :
1.20 mol K₂SO₄ ⇒ __? mL __ of 2.50 M K₂SO₄ ;
____________
Note: 2.50 M K₂SO₄ = 2.50 mol/ L ;
____________
1.20 mol = [tex]\frac{1 L}{2.50 mol}[/tex] ;
The units of "mols" cancel; since "mol / mol = 1 ;
and we have: " [tex]\frac{(1.20*1) L}{(2.50)} = [{\frac{1.20}{2.50}}] L = (0.480) L ;[/tex]
→ {Note: we want to keep the appropriate number of "significant figures"; so we write our answer: "0.48 L" ; as: "0.480 L" .
→ Now, we want to solve for the number of "mL ("milliliters").
→Note the exact conversion: "1000 mL = 1 L ;
So: ("0.480 L") * (1000) = " 480 mL of solution." → which is our answer.
