Answer:
146.3g NaCl (mol NaCl/58.44g NaCl) = 2.50 mol NaCl
1.5M NaCl = 1.5 mol NaCl / 1 L = 2.5 mol NaCl / x L, solve for x
x L = 2.5 mol NaCl / 1.5 mol NaCl = 1.66 L
It gives the answer and all the working.
To put it another way:
Dividing the amount required by the molar mass
we quickly see that 2.5 moles are required.
One litre of 1.5 molar solution gives 1.5 moles
we need a further mole, which is 2/3 of 1.5 so 2/3 of a litre.
Answer:
I think it might be a closed system
The properties of alloys most resemble metal. Copper, tin, fiberglass.
It's any of the almost spherical concentric regions of matter that make up the earth and it's atmosphere, as the lithosphere and hydrosphere.
Hope this helps... If you could, could you mark my answer as brainliest? I'm trying to level lol
