Question

The size of carbon nano tube is $25 \times 10^{- 9} m$ and the size of bacterial cell is $5 μ m$ . Find the ratio of size of bacterial cell to carbon nano tube. Given $1 μ m = 10^{- 6} m$ [3 MARKS]

Solution

Concept: 1 Mark
Application: 2 Mark

Size of carbon Nano tube $= 25 \times 10^{- 9} m$

$S i z e o f b a c t e r i a l c e l l = 5 μ m = 5 \times 10^{- 6} m$

Ratio of bacterial cell to carbon nano tube

$= 5 \times 10^{- 6} m : 25 \times 10^{- 9} m$

$= \frac{5 \times 10^{- 6} m}{25 \times 10^{- 9} m}$

$= \frac{200}{1}$

$= 200 : 1$
