Cells and microorganisms are extremely complex
Answer:
1.47 M
Explanation:
First we <u>convert 86.00 g of NaCl into moles of NaCl</u>, using the <em>molar mass of NaCl</em>:
- 86.00 g ÷ 58.44 g/mol = 1.472 mol NaCl
Then we <u>convert 1000 mL into liters:</u>
Finally we can <u>calculate the molarity of the solution</u>:
- Molarity = moles / liters
- 1.472 mol / 1.0 L = 1.472 M
590 mL = 590 cm³= 0,59 dm³
C = n/V
n = 1,1M × 0,59 dm³
n = 0,649 mol
_____________________________
M KNO₃ = 39g+14g+16g×3 = 101 g/mol
1 mole -------- 101g
0,649 --------- X
X = 101×0,649
X = 65,549g KNO₃

I can tell you about:
- What natura transmutation is
- Which elements suffer natural transmutation
- Some examples of nuclear equation representing natural transmutation
1) Natural transmutation is the transmutation that occurs in nature without intervention of human beings. So, the natural transmutation is the natural decay of elements into other (smaller) elements. The transmutation of the elements consists in the emission of particles (alpha emission, beta emission, positron emission or electron emission) and the obtention of a smaller element.
2) Which elements undergo natural transmutation.
The heavier elements, after lead, are radioactive and so they decay into lighter (smaller) elements. Those elements are unstable due to the relation proton / neutron.
3) Transmutation equation examples
I131 ----> Xe131 + Beta particle
Ra222 ---> Rn218 + 2He4 (same alpha particle)
90Th234 ----> 89Pa234 + beta particle
92U238 ----> 90Th 234 + 2He4 (same alpha particle)
