How many grams are NaCl are required to prepare 200 mL of a 3.10 M solution?

Biology
1 answer:
rodikova [14]2 years ago
6 0

The mass (in grams) of NaCl required to prepare the solution is 36.27 g

<h3>What is molarity?</h3>

Molarity is defined as the mole of solute per unit litre of solution. Mathematically, it can be expressed as:

Molarity = mole / Volume

<h3>How to determine the mole of NaCl</h3>
  • Volume = 200 mL = 200 / 1000 = 0.2 L
  • Molarity = 3.1 M
  • Mole of NaCl =?

The mole of NaCl in the solution can be obtained as follow:

Molarity = mole / Volume

Cross multiply

Mole = Molarity x Volume

Mole of NaCl = 3.1 × 0.2

Mole of NaCl = 0.62 mole

<h3>How to determine the mass of NaCl </h3>

We can obtain the mass of NaCl needed to prepare the solution as follow:

  • Molar mass of NaCl = 58.5 g/mol
  • Mole of NaCl = 0.62 mole
  • Mass of NaCl = ?

Mole = mass / molar mass

Cross multiply

Mass = mole × molar mass

Mass of NaCl = 0.62 × 58.5

Mass of NaCl = 36.27 g

The question is incomplete. The complete question is:

Question: A gene for corn has two alleles, one for yellow kernels and one for white kernels. Cross pollination of yellow corn and white corn results in ears of corn that have an approximately even mix of yellow and white kernels. Which term best describes the relationship between the two alleles?

a) Incomplete dominance

b) Genetic recombination

c) Chimerism

d) Codominance

Answer:

d) codominance

Explanation:

Codominance is a pattern of inheritance when none of the alleles of a gene is able to mask the expression of the other allele of the same gene. When the two alleles are present together in a heterozygous genotype, both are expressed and the phenotype of the heterozygote is different from both the pure breeding parents. In the given example, cross-pollination of yellow corn and white corn results in the ears of corn that have an approximately even mix of yellow and white kernels. This means that the heterozygote expresses both the allele for the corn color. Therefore, it represents codominance.
