A) 41.59 g
B) 415.9 g
C) 4.159 g
D) None of these
Correct Answer: C
Solution :
[\[\because \] Molecular weight of \[CuS{{O}_{4}}.5{{H}_{2}}O\] \[=63.5+32+64+90\]\[=249.5\]] \[6\times {{10}^{23}}\]molecules has weight \[=249.5gm\] \[1\times {{10}^{22}}\] molecules has weight \[=\frac{249.5\times 1\times {{10}^{22}}}{6\times {{10}^{23}}}\] \[=41.58\times {{10}^{-1}}\] \[=4.158\]You need to login to perform this action.
