Question

Which one wiegh most
50 g atom of N
0.1 g atom of àg
1×10^23 atoms of c
5 moles of fe
With explanatio and solved steps

Answer 1

Answer:50 g atom of N

Explanation:To find out the answer,we need to first find out the moles of these elements :-

(i) 50 g atom of N = We know that 1 g atom is the same as 1 mole

                                ∴ 50 g atom of N = 50 mol

(ii) 0.1 g atom of Ag  = Similarly , 0.1 g atom of Ag = 0.1 mol

(iii) 1 * $10^{23}$  = We know that Moles = Given no. of Particles/6 * $10^{23}$

∴ Moles = $\frac{10^{23}}{6*10^{23}}$ = 0.167 mol

(iv) 5 moles of Fe = 5 mol

Finally to find out the answer simply compare all the moles.

∴ 50 g atom of N weighs the most
