Answer:
48g of Magnesium.
Explanation:
We know that:
Mole=given mass/molar mass
Then, moles of aluminum = 54/27 = 2.
A/c to question ,
For 2 moles of magnesium it's mass is 2×24=48g.
Hence, the required mass for same number of magnesium atoms is 48g.

Answer:
Heating causes fluid to expand in volume by reducing its density.
Explanation:
<span>175.5g
</span>Cl(35.5) x 3 = 106.5
Na(23) x 3 = 69
106.5 + 69 = 175.5g
or
0g because sodium and chlorine are not chemically bonded.
