the no of atoms present in. 5g atom of nitrogen is same as the atoms in
Answers
The number of atoms in 1 mole of any substance is 6.022 × 10^23 atoms . This is according to Avogadro's law and it is referred to as Avogadro's number.
Substances with equal moles will have the same the same number of atoms in them.
Moles = mass/ molar mass
i) Moles of 0.5 g nitrogen:
0.5/14
= 0. 0357 moles
ii) moles of 12 C
molar mass of C = 12
= 12/12
= 1 mole
iii) Moles of 32g S
molar mass of S = 32
32/32
= 1mole
iii) Moles of 8 g oxygen
molar mass of O = 16
8/16 = 0.5 moles
iv) Moles of 24 g of Mg
Molar mass of Mg = 24
24/24 = 1 mole
NB: From the list given there is no element with same number of atoms as 0.5 g of Nitrogen. The question should have read 0.5 MOLES of Nitrogen - then the answer would have been 8g of oxygen
Hope it helps u!!
