Answer:
12.044 x 10^23 atoms Na
Explanation:
1 mol Na has 6.022 x 10^23 atoms of Na
2 moles Na have 2 x NA = 2 x 6.022 x10^23 atoms Na
Answer:
False
Explanation:
Water molecules are spread up but slightly, enough that none of the molecules actually move freely around each other. Only gas and plasma molecules are very spread apart.
Answer:
The volume of the gas is 89.60
Explanation:
When converting from moles to volume, you would multiply by 22.4 because 1 mole equals 22.4 liters at STP.
So...
4.0 moles * 22.4 liters =
89.60 liters
