Question

How many microliters are in 7.4 x 10^-61 centimeters?

Answer 1

Answer:

Microliters = $7.4\times 10^{-58}$

Explanation:

SI unit of volume is liter.

$1 dm^{3}=1 liter$ ..............................(1)

1dm=10cm

$1dm^{3} = 1000 cm^{3}$.................(2)

replacing value of $1 dm^{3}$from equation (1) in equation (2)

$1 liter = 1000 cm^{3}$...................(3)

but

$1 liter = 10^{6} microliters$....................(4)

replacing value of 1 liter from equation (3) in equation (4)

$1000 cm^{3} = 10^{6} microliters$

on solving further ,we get

$1 cm^{3} = \frac{10^{6}}{10^{3}}microliter$

$1 cm^{3} = 1000 microliter$

$7.4\times 10^{-61}\times 1000$

Microliters = $7.4\times 10^{-58}$
