Answer:
The answer to your question is letter D. 2.02 g
Explanation:
Data
moles of Ne = 0.100
atomic mass of Neon = 20.18 g
Process
1.- Use proportions to find the answer
20.18 g of Ne ------------------ 1 mol of Ne
x ------------------ 0.1 moles
x = (0.1 x 20.18)/1
x = 2.018
2.- Consider the significant figures
0.100 has three significant figures so the answer must be 2.02 g
Answer:
Energy was released when the sodium and hydroxide ions formed new bonds with the water.
Explanation:
D. Atoms form millions of molecules. :)
solution:
density x volume=mass volume x volume
13.6gml x 3.55ml
thus,the object has a mass of 98.3g
I think the answer you are looking for is .18 moles
