Answer: 0.052moles
Explanation:
number of moles = given mass (g) / molar mass(g/mol)
n=m/M
n= 5.2g/ (40 + 12 + 48)g/mole
n=5.2g/100g/mol
n=0.052 moles
There are many simple ways to prevent erosion. One of the simplest forms of preventing erosion is with vegetation and by establishing root systems that hold the soil together. You can also use geotextiles, fertilizers and also build retainer walls to keep the soil intact and prevent erosion.
Answer:
The appropriate solution is:
(a) n ≈ 900
(b) n ≈ 1165
Explanation:
According to the question,
(a)
The final number of molecules throughout water will be:
=
where, n = number of extractions
Now,
The initial number of molecules will be:
=
=
Final number of molecule,
⇒
(b)
Final molecules of X = left (0.01%)
hence,
⇒
Answer:
Moles= 10.55*10^29ǜ.02*10^23
=1.75*10^6 moles
Moles= mass/molar mass
1.75*10^6=mass/ 183
Mass= 320*10^6 g
The correct answer is it would not have become scientific consensus.
This way, it became the consensus that later led to many amazing treatments and inventions that cured many diseases.
