Questions: A 2.00 L graduated cylinder contains 1.40 L of buffer solution. The density of the buffer solution is 1.02 g / mL. What is the mass in grams of the buffer in the cylinder?

Solution Steps

The problem provides the following values:

• Volume of buffer solution: 1.40 L
• Density of buffer solution: 1.02 g/mL

Since the density is given in g/mL, convert the volume from liters to milliliters. \[ 1.40 \, \text{L} = 1.40 \times 1000 \, \text{mL} = 1400 \, \text{mL} \]

Use the formula for mass: \[ \text{Mass} = \text{Density} \times \text{Volume} \] \[ \text{Mass} = 1.02 \, \text{g/mL} \times 1400 \, \text{mL} \] \[ \text{Mass} = 1428 \, \text{g} \]
