Answer:
If you mean the number of atoms in 8g of oxygen, it's 3.011 x 10^23 atoms.
Explanation:
Convert the grams to moles. 8 grams of oxygen is 0.5 moles. Then multiply the number of moles by Avogadro's number: 6.022 x 10^23.
Answer:
The level of the water will be higher for 100g Al because occupy more space than gold.
Explanation:
To understand this problem, we must know Archimedes' principle:
"A body that is submerged in a fluid produce a bouyant force equal to the weight of the fluid that the body displaces". The volume of the body is equal to the volume displaced in the liquid.
Now, as gold is heavier than aluminium, 100g of Al have more volume than 100g of gold, than means:
<h3>The level of the water will be higher for 100g Al because occupy more space than gold.</h3>
