How many moles of CH3OH are there in 43.7 mL of 0.400 M CH30

The number of moles of CH₃OH present is 0.01748 mole

From the question,

We are to determine the number of moles of CH₃OH that are in 43.7 mL of 0.400 M CH₃OH

Using the formula

Number of moles = Concentration × Volume

From the question

Concentration of CH₃OH = 0.400 M

Volume of CH₃OH = 43.7 mL = 0.0437 L

∴ Number of moles of CH₃OH present = 0.400 × 0.0437

Number of moles of CH₃OH present = 0.01748 mole

Hence, the number of moles of CH₃OH present is 0.01748 mole

0.0174 mol

Explanation:

Molarity is (moles of solute)/(liters of solvent).  So, to find moles you need to multiply liters by molarity.

0.0437 L × 0.400 M = 0.0174 mol

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
