2.) convert 200.46 miles per hour to km/s

5.) convert 1.745 * 10^-5 m^3 to pints.

7.) convert 1.5 square miles to dm^2.

Are these really chemistry questions?

google can do these, or visit

Yes they are Chemistry Questions. I have Chemistry rn and these are the questions that we are doing.

These will give me ANSWERS ONLY.Can someone explaint to me how to do these????

Jake seems to be having similar questions...

Hmmm!! Emily and Jake seem to be posting from the same computer!

As Steve said above, use Google. Here's one:

Look up the others in the same way. Go to Google and enter this or whatever you need:

how to convert square miles to dm^2

There are always several basic conversion units. For example,

convert 1.745 * 10^-5 m^3 to pints.

1 gallon = 231 in^3
1 in = 2.54 cm

so, just start converting, making sure the units cancel correctly:

1.745*10^-5 m^3 * (100cm/m)^3 * (1in/2.54cm)^3 * 1gal/231in^3 * 8pt/gal = 0.0369 pt

makes sense, since you have about 17cc, which is about 1/30 pint.
