Some Basic Concepts of Chemistry question

2020 · 6 Sep · Shift 1 · Q18

JEE MainChemistrySome Basic Concepts of ChemistryMCQ+4 / −1
A solution of two components containing n1n_1n1​ moles of the 1st component and n2n_2n2​ moles of the 2nd component is prepared. M1M_1M1​ and M2M_2M2​ are the molecular weights of component 1 and 2 respectively. If d is the density of the solution in g mL–1, C2C_2C2​ is the molarity and x2x_2x2​ is the mole fraction of the 2nd component, then C2C_2C2​ can be expressed as :
  1. A
    C2=1000x2M1+x2(M2−M1){C_2} = {{1000{x_2}} \over {{M_1} + {x_2}\left( {{M_2} - {M_1}} \right)}}C2​=M1​+x2​(M2​−M1​)1000x2​​
  2. B
    C2=1000dx2M1+x2(M2−M1){C_2} = {{1000d{x_2}} \over {{M_1} + {x_2}\left( {{M_2} - {M_1}} \right)}}C2​=M1​+x2​(M2​−M1​)1000dx2​​
  3. C
    C2=dx2M1+x2(M2−M1){C_2} = {{d{x_2}} \over {{M_1} + {x_2}\left( {{M_2} - {M_1}} \right)}}C2​=M1​+x2​(M2​−M1​)dx2​​
  4. D
    C2=dx1M1+x2(M2−M1){C_2} = {{d{x_1}} \over {{M_1} + {x_2}\left( {{M_2} - {M_1}} \right)}}C2​=M1​+x2​(M2​−M1​)dx1​​
