What volume of 0.250 M solution can be prepared from 16.0 g of potassium carbonate?
What volume of 0.250 M solution can be prepared from 16.0 g of potassium carbonate?
READ Knowns mass= 16.0 g K_2CO_3
M = 0.250 mol/L
Molar mass K_2CO_3 = 138.2 g/mol
PLAN Find the volume that can be prepared from 16.0 g K_2CO_3
Solution map: gK_2CO_3→ mol K_2CO_3 → L solution
CALCULATE (16.0 \cancel{g K_2CO_3} ) ( \frac{1 \cancel{mol K_2CO_3} }{138.2 \cancel{g K_2CO_3} } ) ( \frac{1 L}{0.250 \cancel{mol K_2CO_3}} ) = 0.463 L
