We must know that molarity is a unit for concentration and it is expressed as:
molarity = moles / liters
The molarity is 100 millimolar, or 0.1 molar. The volume is 250 ml, or 0.25 liters. Using the formula above, we find the moles of benzoic acid required.
moles = molarity * liters
moles = 0.1 * 0.25
moles = 0.025
Next, we know that the molar mass for benzoic acid is 122.12 g/mol and the moles of a substance are given by:
moles = mass / molar mass
mass = moles * molar mass
mass = 0.025 * 122.12
mass = 3.05 grams
You will need to weigh out 3.05 grams of benzoic acid
Answer:
<h2>It'll float</h2><h2>Less than 1g/cm3 it'll float in water </h2>
