Answer:
hi buddy!! here is ur ans: carbon atoms
The molarity of the aqueous acid solution : 0.0101 M
<h3>Further explanation </h3>
Titration is a procedure for determining the concentration of a solution by reacting with another solution that is known to be concentrated (usually a standard solution). Determination of the endpoint/equivalence point of the reaction can use indicators according to the appropriate pH range
Acid-base titration formula
Ma. Va. na = Mb. Vb. nb
Ma, Mb = acid base concentration
Va, Vb = acid base volume
na, nb = acid base valence (amount of H⁺, OH⁻)
Va=12.5 ml
na = 2 (H₂SO₄⇒2H⁺+SO₄²⁻⇒2 ion H⁺)
Mb=0.015
Vb=16.8 ml
nb = 1(LiOH⇒Li⁺+OH⁻⇒1 ion OH⁻)
The molarity of the acid(Ma) :
Molar mass CaCl₂ = 111.0 g/mol
number of moles:
n = mass of solute / molar mass
n = 85.3 / 111.0
n = 0.7684 moles of CaCl₂
M = n / V
0.788 M = <span>0.7684 / V
</span>
V = 0.7684 / 0.788
V = 0.97512 L
hope this helps!
Yes this is true as in cold conditions our body doesn't feel the urge of water therefore we may become dehydrated not even knowing about it and of course in hot coditions we sweat therefore we loose water.
Hope this helps :).
