This material has a density of 1 g/cm3.
(since 12.48 g/ 12.48 cm3 = 1 g/cm3)
Therefore, this material is water.
You multiply the molarity by the volume in litres.
Explanation:
Molarity is the number of moles of a substance in one litre of solution. The official symbol for molarity is “c” (concentration), but many people use the old symbol “M”.
M
=
n
V
, where
n
is the number of moles and
V
is the volume in litres.
We can rearrange this equation to get the number of moles:
n
=
M
×
V
Example
:
How many moles of
NaCl
are contained in 0.300 L of 0.400 mol/L
NaCl
solution?
Solution:
n
=
0.300
L soln
×
0.400 mol NaCl
1
L soln
=
0.120 mol NaCl
Answer:
C
Explanation:
Chlorine gas is Cl2.
Molecule has two atoms of the same kind.
The molar mass of a substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units....
hope that helps
so i think that it is false because base on the statement above si the decision is yours just read it thanx
