Question

Anushka, Karuna, Sohan and Krishna having a container with 6 moles of F atoms, 6 moles of $F_2$ molecules, $12.044\times {10}^{23}$ number of F atoms and $6.022\times {10}^{23}$ number of $F_2$ molecules respectively.
Which among the four will have the same amount of F atoms in grams?

• A. Karuna and Krishna
• B. Sohan and Krishna
• C. Anushka and Karuna
• D. None of these

Answer 1

The correct option is B Sohan and Krishna

In Sohan's case, $12.044\times {10}^{23}$ atoms of ${}^{\prime }{F}^{\prime }$ is present. In Krishna's case, $6.022\times {10}^{23}$ no. of '$F_2$' molecules are present. Means one $F_2$ molecule gives $2^{\prime }{F}^{\prime }$ atoms. So $6.022\times {10}^{23}\times 2=12.044\times {10}^{23}$ atoms of ${}^{\prime }{F}^{\prime }$ is present here. So, no. of ${}^{\prime }{F}^{\prime }$ atoms is same in case of Sohan and Krishna.
