How much positive charge is in 1.4 kg of oxygen? The atomic weight (15.9994 g) of oxygen contains Avogadro’s number of atoms, wi
Cerrena [4.2K]

Answer:

6.7511\times 10^7\ C

Explanation:

The atomic weight of oxygen = 15.9994 g

This mass corresponds to 1 mole of the oxygen atoms.

Thus,

15.9994 g mass of oxygen contains 6.02\times 10^{23} atoms of oxygen.

1.4 kg = 1400 g ( 1 kg = 1000 g)

So,

1400 g mass of oxygen contains \frac {6.02\times 10^{23}}{15.9994}\times 1400 atoms of oxygen.

Number of atoms in 1400 g of oxygen = 526.769754\times 10^{23}

Also, 1 atom of oxygen contains 8 protons

Charge of 1 proton = + 1.602\times 10^{-19}\ C

So, Charge on 1 atom of oxygen = 8\times 1.602\times 10^{-19}\ C

Thus,

Charge on 526.769754\times 10^{23} atoms of oxygen = 526.94476\times 10^{23}\times 8\times 1.602\times 10^{-19}\ C=6.7533\times 10^7\ C

Thus, positive charge in 1.4 kg of oxygen = 6.7511\times 10^7\ C

How many neutrons does the following nuclide have? 253/100 Fm A. 253 B. 100 C. 153 D. none of these
lara [203]
I believe the correct answer is C. The number of neutrons in the <span>253/100 Fm would be 153. The numbers beside Fm are used to determine this. Two hundred fifty three represents the mass number which is the sum of protons and neutrons in the nuclide while 100 represents the atomic number which is the number of protons. Therefore,

253 = neutrons + 100
neutrons = 153</span>
