To make a 6.50M solution, how many moles of solute will be needed if 12.0 liters of solution are required
avanturin [10]

Answer:

78 moles of the solute

Explanation:

From the question;

  • Molarity of the solution is 6.50 M
  • Volume of the solution is 12.0 L

We want to determine the number of moles needed

We need to know that;

Molarity = Number of moles ÷ Volume

Therefore;

Number of moles = Molarity × Volume

Hence;

Number of moles = 6.50 M × 12.0 L

                             = 78 moles

Thus, the moles of the solute needed is 78 moles

In a Punnett square, lower case letters are recessive alleles and upper case letters are dominant alleles. So, "tt" would mean that both alleles are recessive. In comparison, "Tt" would mean that one allele is dominant and one is recessive. Therefore zero would be tall as their is no T trait from either parents.

You are conducting a plant growth experiment and need to generate a solution with growth factor, auxin or indole-3-acetic acid.
Yuki888 [10]

Answer:

7,01 g of indole-3-acetic acid

Explanation:

The milimolar concentration (mM) is defined as the ratio of milimoles per Liter of solution. 400mM means 400mmoles / L that is the same of <em>0,4mol / L</em>

100mL are <em>0,1L</em>. Using these values:

0,1L × (0,4mol / L ) = 0,04moles of indole-3-acetic acid.

As the MW of the molecule is 175,2 g/mol:

0,04mol × (175,2g / mol) = <em>7,01 g of indole-3-acetic acid</em>

<em></em>

Thus, <em>you need 7,01 g of indole-3-acetic acid to generate your solution</em>.

I hope it helps!
