Answer: Salt crystals are a part of isometric crystal system.
Explanation: There are in total 7 crystal systems:
Salt has a molecular formula of NaCl which crystallizes in face-centered cubic system and this system comes under cubic crystal system.
Another name for cubic crystal system is isometric crystal system because in this system all the sides and angles are equal.
Mass and weight are very similar, but different.
Mass is how much matter an object contains. Weight is how much force gravity is putting on an object.
We're gonna use this formula:
P₁ = 177 atm
T₁ = 298 (Convert Celsius to kelvins by adding 273)
P₂ = ?
T₂ = 468 (195 + 273)
We can cross-multiply or multiply both sides by 468
I'm gonna go with the latter
The coffee is the solvent. The sugar is the solute. The sweetened coffee is the solution.
Molarity of Unknown Acid = 0.1332 M
Data for solving problem:
Molarity of base in buret (M₁)= 0.1517 M
volume of the acid in Erlenmeyer flask (V₂)= 25.0 mL
Volume of the base in the buret (V₁) = final volume of buret - initial volume in buret
final volume of buret = 22.5 mL
initial volume in buret = 0.55 mL
Volume of the base in the buret (V₁) = 22.5 mL -0.55 mL = 21.95 mL
Volume of the base in the buret (V₁) = 21.95 mL
Molarity of Unknown acid in the Erlenmeyer flask (M₂) = To be find
It is acid base titration and formula for this titration is as follows:
Molarity of base x Volume of base = Molarity of acid x volume of acid
it can be written as
M₁V₁ = M₂V₂ -------------------- equation (1)
we have to find M₂
so by rearrangment the equation (1)
M₁V₁ / V₂ = M₂ ------------------ equation (2)
put the values in equation in equation (2)
M₂ = 0.1517 M x 21.95 mL / 25.0 mL
M₂ = 3.3298 /25.0
M₂ = 0.1332 M
so the Molarity of Unknown acid is <u>0.1332 M</u>
