Question

Calculate the following figures:

47. m = ______ cm
8.17 x 105 m = ________ km
329 g = ________kg
8.50 km = ________ m
0.32 L = ________ mL
0.000371 km = ________ m
680 mm = ________ cm
210 g = _________ mg
7001 L = ________ nL
0.001 m = __________ mm
28. 0.000001 L = __________ µL

Answer 1

First of all you need to know the following conversions, so you can solve any then.

`1km=10^3m=10^5cm=10^6mm=10^9micrometer`
Knowing that each km contain 1000m and each meter contain 100cm and each cm contain 10 millimeters and each millimeter contain 1000 micrometer.
Similarly in Liters,

`1L= 10^3mL= 10^6microL=10^9nanoL`
Similarly in grams,

`1g=10^3mg`

So after this all it should be easy to calculate the answers;

`47m=47*10^2cm`

`8.17*10^5m=8.17*10^5* 10^(-3)km =8.17*10^2km=817km`

`329g=329* 10^(-3) kg`

`8.5km=8.5*10^3m=8500m`

`0.32L=0.32*10^3mL=320mL`

`0.000371km=0.000371*10^3m=0.371m`

`680mm=680* 10^(-1) cm=68cm`

`210g= 210*10^3 mg`

`7001L=7001*10^9nL`

`0.001m=0.001*10^3mm=1mm`

`0.00001L=1* 10^(-6)L=1*10^(-6)*10^(6)microL=1microL`

Hope this helps!

Answer 2

47. m = _47*10² cm =4700 cm
8.17 x 105 m = 857.85 m= 0.85785 km
329 g = 329*10⁻³kg=0.329 g
8.50 km = 8.50*10³ m=8500 km
0.32 L = 0.32*10³ mL=320 mL
0.000371 km = 0.000371*10³ m = 0.371 m
680 mm = _68_______ cm
210 g = __0.210_______ mg
7001 L = _7001*10⁹nL=7.001*10¹² nL
0.001 m = _______1___ mm
28. 0.000001 L = __1________ µL
