The concentration of CH3OH in the solution is 2.18M
HOW TO CALCULATE MOLARITY:
- The molarity of a solution can be calculated by dividing the number of moles by its volume as follows:
- Molarity {M} = no. of moles (mol) ÷ volume (L)
- According to this question, 35.0 g of CH3OH (MM = 32.0 g/mol) are dissolved in 500.0 mL of solution. The number of moles of methanol is calculated as follows:
no. of moles = 35g ÷ 32g/mol
no. of moles = 1.09mol
- Molarity = no. of moles ÷ volume
Volume = 500mL = 0.500L
Molarity = 1.09mol ÷ 0.500L
Molarity = 2.18M
Therefore, the concentration of CH3OH in the solution is 2.18M

The appropriate answer is D. Fossils of terrestrial life forms would be found in this region. Sand and silt are typically deposited by fluvial or river processes which occur on land. Sand and silt are fine grained materials which would also suggest that the environment may possibly be a flood plain. Flood plains are located in the lower course of rivers; close to where they empty into the sea. This scenario fits with the fact that three was a drop in sea level which would expose land closest to the coast. <span />
Answer: A primary consumer that obtains its energy from the consumption of plants
.
Explanation: This is the only option that makes sense. A monarch is not a producer since it is not a plant. A monarch is not a decomposer of course. Why is it a primary consumer? because monarchs eat from a plant and then are eaten by a secondary consumer.
Answer: number of protons plus the number of neutrons
