How many moles of sugar are in a 10 mL sip of a soft drink whose sucrose concentration is 0.375 M?

1. Rearranging the definition of molarity gives moles of solute = molarity x litres of solution. 2. Convert the volume: 10 mL x 1 L / 1000 mL = 0.010 L. 3. Multiply: 0.375 mol/L x 0.010 L. 4. The result is 0.004 mol of sugar. 5. The value 0.0375 mol comes from using 0.100 L instead of 0.010 L, a decimal place out. _Source: OpenStax Chemistry (CC BY 4.0), Ch 3 "Composition of Substances and Solutions", section 3.3 Molarity_
