A cube has a mass of 9 grams and each side is 3 cm3. What is the density of the sample? a.0.33 g/mL

b.36g/mL

c.3g/mLd.18g/mL

Im begging someone to help, Ill mark brainlist!!!

a. 0.33 g/mL

Explanation:

We already know what the mass is (9 grams) so we have to find the volume of the cube next.

Volume = lwh

             =(3)(3(3)

             = 27

To find density, you have to find mass/volume

density = mass /volume

density = 9 g /27 mL             (cm 3 and mL are basically the same thing)

            = 0.33 g/mL

each  column  of the  table  is called a group. elements in a group share similar properties. groups are  read  from  top  to  bottom. metal. metalloid. nonmetal. solid. liquid. gas. fe. hg. o.  2. 3. 4. 5. 6. 7. 8. 9.  2. beryllium. 9.012. 4.  sodium. 22.990.  11. 3.  magnesium. 24.305.  12.  potassium. 39.098.  19. 4.  calcium. 40.078.  20. i guess  i  

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
