Conversions involving algebra

[Symphonie]

Hello. I'm not completely sure how to do all of this yet because I'm currently learning this all over again in Physics before we start going into more advanced things. There are a few questions that I had on one of my worksheets that I wasn't too sure about with my answers. I was wondering what the answers were and what methods you use to get these answers. The questions are:

1) 70.5 cm^3 to mL (This one I didn't have any idea how to do.)

2) 8.22 x 10^-5 micrometers to Ã… (Ã…= 1x 10^-10 m)

3)9.92 x 10 ^7 mm to m

Any help is appreciated. Thanks in advance!

1) 70.5 ml.

Remember that the SI system defines one liter is the volume of 1,000 cubic centimeters. Therefore 1 cubic centimeter will be one milliliter.

2) 0.822 Ã….

You need to remember to convert 8.22 x 10^-5 micrometers to meters, and then divide by 1x10^-10 m/Ã….

(8.22 x 10^-5 µm) · (1 x 10^-6 m/µm) = 8.22 x 10^-11 m

8.22 x 10^-11 m / 1 x 10^-10 m/Ã… = 0.822 Ã…

3) 9.92 x 10^-10 m

There are 1 x 10^-3 mm/m, so:

(9.92 x 10^-7) · (1 x 10^-3) = 9.92 x 10^-10
