If 35.0 g of CH3OH (MM = 32.0 g/mol) are dissolved in 500.0 mL of solution, what is the concentration of CH3OH in the solution?​
astra-53 [7]

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

In a population of seals, most of the seals have similar coloring. However, one seal has albinism. This seal is white and is alm
erica [24]
The answer is gene mutation.

Albinism is a congenital disorder characterized by a complete or partial absent of pigment in skin, eyes or hair. It is a recessive disorder, which means that parents must not have the disorder. But if both of them carry a recessive allele, and offspring inherit the recessive alleles from mother and father, the offspring will have albinism. Anyway, it is pretty rare, since it is the recessive trait, and most of the offspring will have normal coloring.
