The density of the solution is 2.15 g mL1, then mass of 2.5 mL solution in correct significant figures is :
- A53.75 g
- B5375 103 g
- C5.4 g
- D5.38 g
View written solutionFree
Correct answer: C
Mass = Volume $\times$ Density
= 2.5 $\times$ 2.15
= 5.375 g
Since 2.5 has two significant figures, so the mass of solution in correct significant figures will be 5.4 g.
