Directions : In the following question more than one of the answers given may be correct. Select the correct answer and mark it according to the code:
Which of the following have the same mass? (1) 0.1 mol of\[S{{O}_{2}}\]gas (2)\[6.02\times {{10}^{22}}\]molecules of\[S{{O}_{2}}\]gas (3)\[1.204\times {{20}^{23}}\]molecules of\[{{O}_{2}}\]gas (4) 0.1 mol of\[{{O}_{3}}\]gasA) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: A
Solution :
0.1 mol of\[S{{O}_{2}}\] gas = 6.4 g \[6.02\times {{10}^{22}}\]molecules of\[S{{O}_{2}}\] =0.1 mol of \[S{{O}_{2}}=6.4g\] \[1.204\times {{10}^{23}}\]molecules of\[{{O}_{2}}=\] 0.2 mol of\[{{O}_{2}}=\]6.4g 0.1 mol of\[{{O}_{2}}\] gas = 3.2gYou need to login to perform this action.
