Answer to Question #160550 in General Chemistry for marky

Question

Calculate the molarity when 250 g of C6 H12 O6 is dissolved in 2500 ml of water.

Answer 1

M(C₆H₁₂O₆) = 180 g/mol

n(C₆H₁₂O₆) $= \frac{250}{180} = 1.388 \;mol$

Proportion:

1.388 mol – 2500 mL

x – 1000 mL

$x = \frac{1.388 \times 1000}{2500} = 0.55 \;M$

Answer: 0.55 M
