I need Chemistry help! ?

Question

I'm having a lot of trouble doing these problems. Please help me!

1. Convert 2.5 cm into m.

2. Convert 462 kL into L.

3. Convert 0.256 kg into cg.

4. If an object has a volume of 20 kL, how many mL does it occupy?

5. A table top is 3.0 m x 0.75 m x 4.0 cm, what is its volume in cm^2?

6. 0.0025 L is how many cc's?

7. Copper has a density of 8.9 g / cm^3. If a chunk of copper has a volume of 2.1 liters, what is the mass of copper?

8. A copper block has a mass of 305 g, what is its volume?

**If anyone has a conversion table, I really need one**

Thanks so much

Answer 1

1. 2.5cm = 0.025m

2. 462kL = 462000L

3. 0.256kg = 256g (cg?)

4. 20kL = 20000L = 20000000mL

5. 9cm^2 (not volume, and btw this is extremely small for a table)

6. 0.0025L = 2.5 cc (same as mL)

7. mass of copper is 2100*8.9g = about 1.8kg

8. volume = about 35 cc/mL

Answer 2

dude your phone can probably do all this. come on
