Answer: Hard

Explanation:

The upper part of the mantle is hard as it contains thick rock layers. The mantle's upper layer and the crust make up a brittle and rigid rock that's referred to as the Lithosphere.

The upper mantle starts below the Earth crust and then stops at the start of the lower mantle. We should note that the upper mantle results in the movement of the tectonic plates.

The best fit curve line to an absorbance vs. concentration plot for standard solutions of a dye has a slope of 0.1815 mL/mg and
omeli [17]

Answer:

The concentration of dye is 2.29 mg/mL.

Explanation:

According to Beer's law the absorbance (A) of a solution is proportional to its concentration (c). The best fit curve line to an A vs. c plot has a slope of 0.1815 mL/mg and intercept of 0.0477. The resulting equation is:

A =  0.0477 + 0.1815 mL/mg . c

If a solution has an absorbance of 0.464, the concentration of dye will be:

0.464 =  0.0477 + 0.1815 mL/mg . c

c = 2.29 mg/mL
