Hey I need help with this element, compound, and mixtures worksheet
Alika [10]

We should describe a little bit the legend.

A - Element - we should have circles with same color and not bonded together (argon gas).

B - Compound - here we may have circles with same or different color bonded together (water or oxygen which is a diatomic molecule).

C - Mixture of elements - circles with different colors not not bonded together (mixture of noble gases).

D - Mixture of compounds - circles with same or different color bonded together but we should see two or more types of connectivity between circles (mixture of water and ethanol).

E - Mixture of elements and compounds - circles with same or different color bonded together mixed with circles with same color and not bonded together (a mixture between oxygen which is a diatomic molecule and noble gas like argon).

Now we may answer the question:

1) B

2) C

3) D

4) D

5) A

6) B

7) B

8) E

9) E

Mass in grams of 6.023×1023 atom of Ca​
Mademuasel [1]

Answer:

\boxed {\boxed {\sf 40.08 \ grams}}

Explanation:

First, find the molar mass of calcium (Ca). This can be found on the Periodic Table.

  • 40.08 g/mol

Next, find the number of moles.

Avogadro's Number tells us the number of atoms in one mole.

  • It is 6.023*10²³

Therefore, there are 6.023*10²³ atoms in 1 mole.

We have 6.023*10²³ atoms of calcium, so it must also be 1 mole of calcium.

Finally, find the mass. Set up a proportion using the molar mass of calcium.

1 \ mol \ Ca * \frac{40.09 \ g}{1 \ mol \ Ca}

Multiply. The moles (mol Ca) will cancel.

1 * 40.08 \ g

40.08 \ g

There are <u>40.08 grams </u>in 6.023*10²³ atoms of calcium.
