A liquid in the lab has a density of 1.24 g/cm^3. What is the mass of 250 mL of this liquid?

• A. 310 g
• B. 155 g
• C. 1.24 g
• D. 200 g

Answer: (A)

Verified step by step guidance

1. Identify the given information: density \(\rho = 1.24\ \text{g/cm}^3\) and volume \(V = 250\ \text{mL}\). Note that 1 mL is equivalent to 1 cm\(^3\), so the volume can be directly used in cm\(^3\).
2. Recall the formula that relates mass, density, and volume: \(m = \rho \times V\), where \(m\) is mass, \(\rho\) is density, and \(V\) is volume.
3. Substitute the known values into the formula: \(m = 1.24\ \text{g/cm}^3 \times 250\ \text{cm}^3\).
4. Perform the multiplication to find the mass in grams (do not calculate the final number here, just set up the expression).
5. Interpret the result as the mass of the liquid in grams corresponding to the given volume and density.
