Answer:
1,869.97 grams of Be(NO3)2
Explanation:
Be(NO3)2 = Be N2 O6
Be=9.012182g/mole
N2=28.0134g/mole
O6=96g/mole
therefore Be(NO3)2 gives you 187.56g in one mole
so 9.97 moles means there is 9.97 times more
9.97mole Be(NO3)2 * 187.56g Be(NO3)2/1mole Be(NO3)2 = 1,869.97g of Be(NO3)2
Answer: science is the systematic way of gaining knowledge about nature
The number 16 next to the elemental symbol of Nitrogen
which is N indicates the mass number of the element. Now the atomic number of N
is 7, this is also equal to the number of protons or electrons in the nucleus. So
the balance is 16 – 7 = 9 which is being occupied by the neutrons. Therefore
the number of neutrons is:
