A.genetic modification of food helps it grow more easily in certain areas

Explanation:

The statement genetic modification of food helps it grow more easily in certain areas is a form of agricultural research that is very accurate.

Genetically modifying food is common practice in order to encourage desirable and sustainable traits in plant species.

Drought resistant breeds can tolerate a much lower level of water in some specific areas.
Disease resistant breeds are more adapted to outbreaks of plant epidemics.
Overall, genetic modification of food helps them to grow and produce better.

3. If the percent by volume is 2.0% and the volume of solution is 250 mL, what is the volume of solute in solution? (1 point) 0.

igor_vitrenko [27]

Volume percent = Volume of solute
----------------------------------
Volume of the solution

   2 Volume of the solute
------- =   ------------------------------
100 250

Volume of the solute = 2 x 250
------------
100

= 5 mL.

Hope this helps!

How many moles of Chromium is in 4.41 ×10^24 atoms

zalisa [80]

7.32 moles of Chromium is present in 4.41 × 10²⁴ atoms.

<h3>How to find the number of moles ?</h3>

Number of moles = $\frac{\text{Given number of atoms}}{\text{Avogadro's Number}}$

<h3>What is Avogadro's Number ?</h3>

Avogadro's number is the number of particles in one mole of substance. 6.022 × 10²³ is known as Avogadro's Constant / Avogadro's Number.

Avogadro's Number = 6.022 × 10²³

Now put the values in above formula we get

Number of moles = $\frac{\text{Given number of atoms}}{\text{Avogadro's Number}}$

= $\frac{4.41 \times 10^{24}}{6.022 \times 10^{23}}$

= 7.32 moles

Thus from the above conclusion we can say that 7.32 moles of Chromium is present in 4.41 × 10²⁴ atoms.

PLEASE HELP----

Actual yield of Fe2(So4)3 = 18.5g

2FePo4 + 3Na2SO4 -> Fe2(SO4)3 + 2Na3PO4

Mole of FePO4 = mass of it / its molar mass =
25 g / (55.8 + 31 + 16*4) = 0.166 mol

every 2 mole of FePO4 will form 1 mole of Fe2(SO4)3

Mole of Fe2(SO4)3 produced = 0.166 / 2 = 0.0829 mol

0.0829 * (55.8*2 + 3*(32.1+ 16*4)) = 33.148 g of Fe2(SO4)3

18.5 / 33.148 * 100 = 55.8%
