A gold-colored pebble is found in a stream. Its mass is 23.2 mg and its volume is 1.20 mm3. What is its density in grams per cub
Lilit [14]

Answer:

The density in g/cm3 is 1.9333(put a line above the 3's to show it's repeating).

And no it is not gold because the density of gold in g/cm3 is 19.3.

Explanation:

Divide the mass by the volume in order to get an object's Density.

so, 23.2 divided by 1.20 mm3

=1.93333333 g/cm3

That is the density then you find out the density of gold in grams per cubic centimeter, that is 19.3 g/cm3

For example, gold will always have a density of 19.3 g/cm3; if a mineral has a density other than that, it isn't gold.

uppose you are titrating an acid of unknown concentration with a standardized base. At the beginning of the titration, you read
victus00 [196]

Answer:

<u>20.25 mL.</u>

Explanation:

The volume of base required for the titration can be derived by removing the base titrant volume from the volume at endpoint.

i.e Final volume - initial volume

= (22.08 - 1.83)mL

<u>= 20.25 mL.</u>

<em>(Repeat and average volume results for accuracy.)</em>

KClO₃ → Kelt Oz
cestrela7 [59]

Answer:

5.2 moles of  KClO₃  are needed

Explanation:

Given data:

Number of moles of potassium chlorate needed = ?

Number of moles of O₂ formed = 7.8 mol

Solution:

Chemical equation:

2KClO₃      →     2KCl + 3O₂

now we will compare the moles of KClO₃ and  O₂.

                   O₂        :         KClO₃    

                    3          :           2

                   7.8        :          2/3×7.8 = 5.2

5.2 moles of  KClO₃  are needed.
