Answer:
1.31
Explanation:
Given,
Given mass of Zn = 15 g
Volume of solution = 175 ml
Mass of Zn = 65.4
No. of moles of solute
= Given mass of Zn / mass of Zn
= 15 / 65.4
= 0.22 ( approximately )
Formula : -
Molarity
= No. of moles of solute / Volume of solution (L)
= 0.22 / ( 175 / 1000 )
= 0.22 / 0.175
= 1.257
= 1.31 ( approximately )
