Question

What is the mass in grams of the buffer solution in the 2.00 L graduated cylinder, given that it contains 1.40 L of solution with a density of 1.02 g/mL?

a) 1.43 g
b) 1.44 g
c) 1.46 g
d) 1.49 g

Answer 1

The mass of the buffer solution in the 2.00 L graduated cylinder is 1.43 g.

Step-by-step explanation:

To find the mass in grams of the buffer solution in the 2.00 L graduated cylinder, we need to consider the volume of the solution and its density. The mass of the buffer solution in the 2.00 L graduated cylinder is 1.43 g. Given that the solution has a density of 1.02 g/mL and a volume of 1.40 L, we can calculate the mass using the formula:

Mass = Volume × Density

Mass = 1.40 L × 1.02 g/mL = 1.428 g

The mass of the buffer solution in the 2.00 L graduated cylinder is 1.43 g. Rounding off to 2 significant figures, the mass of the buffer solution in the 2.00 L graduated cylinder is 1.43 g.
