Which of the following solutions would be expected to contain the greatest number of solute particles (molecules or ions) ?

• A) 1 liter of 0.5 M NaCl
• B) 1 liter of 1.0 M NaCl
• C) 1 liter of 1.0 M glucose
• D) 1 liter of 1.0 M NaCl and 1 liter of 1.0 M glucose will contain equal numbers of solute particles.
