Calculate the mole fraction of the total ions in an aqueous solution prepared by dissolving 0.400 moles of CaI2 in 850.0 g of wa
Evgesh-ka [11]

Answer:

0.00840

Explanation:

The computation of the mole fraction is as follow:

As we know that

Molar mass = Number of grams ÷ number of moles

Or

number of moles = Number of grams ÷ molar mass

Given that

Number of moles of CaI2 = 0.400

And, Molar mass of water = 18.0 g/mol

Now  Number of moles of water is

= 850.0 g ÷ 18.0 g/mol

= 47.22 mol

And, Total number of moles is

= 0.400 + 47.22

= 47.62

So, Molar fraction of CaI2 is

= 0.400 ÷ 47.62

= 0.00840

PLEASE HELPP ______ consist of one large main root with smaller roots branching off, while _____ consist of several main roots t
Kay [80]

fibrous roots; taproots

Explanation:

A taproot root consists of one large main root with smaller roots that branches off into the soil, while the fibrous roots consists of several main roots that branches off to form one mass of roots.

  • The root system in plants helps them to absorb water and other nutrients from the soil.
  • A taproot is much more like extension of stem that penetrates into the ground.
  • It tapers at the end with many other smaller roots branching and networking from it.
  • The fibrous root is a series of roots directly from the stem that independent of one another.
  • Roots are used by plants for anchorage into the soil.
