Which statement is true?
docker41 [41]
I am pretty sure that the statement which is true is A. a molecule having a covalent bond can be ionic. I choose this option because you usually ca see how electons of polyatomic ions are being covalenr and gain or loose ionic electrons in order to accomplish the octet.<span>

-You wish to make a 0.203 M hydrochloric acid solution from a stock solution of 6.00 M hydrochloric acid. How much concentrated
lubasha [3.4K]

For all three questions, we will use the fact that

  • molarity = (moles of solute)/(liters of solution)

1) For 175 mL of solution at 0.203 M, this means that:

  • 0.203 = (moles of solute)/0.175
  • moles of solute = 0.035523 mol

Considering the hydrochloric acid solution, if we have 0.035523 mol, then:

  • 6.00 = 0.035523/(liters of solution)
  • liters of solution = 0.035523/6.00 = 0.0059205 = <u>5.92 mL (to 3 sf)</u>

<u />

2) If there is 20.3 mL = 0.0203 L, then:

  • 8.20 = (moles of solute)/0.0203
  • moles of solute = 0.16646 mol

This means that the molarity of the diluted solution is:

  • 0.16646/(0.200) = <u>0.832 M (to 3 sf)</u>

<u />

3) If we need 1.50 L of 0.700 M solution, then:

  • 0.700 = (moles of solute)/1.50
  • moles of solute = 1.05 mol

Considering the 9.36 M acid solution, from which we need 1.05 mol of perchloric acid from,

  • 9.36 = 1.05/(liters of solution)
  • liters of solution = 1.05/9.36, which is 0.11217948717949 L, or <u>112 mL (to 3 sf)</u>

How many moles in Co are there in 6 billion Co atoms
nasty-shy [4]
Hello there!

<span> Use Avogadro's number, 1 mol = 6.02 x 10^23 atoms. 
</span>Convert atoms to moles and you get:

<span>9.97x10^(-15) moles Co
