You can use this formula to solve for density--> Density= PM/ RT, where P is pressure, M is molar mass, R is the gas constant and T is temperature.
P= 1.75 atm
M= 16.01 g/ mol
R= 0.0821 atm·L/ mol·K
T=337 k
density= (1.75 x 16.01)/ (0.0821 x 337)= 1.01 g/L
Mass of solute in g :
1 kg ---------- 1000 g
0.098 kg ------ ??
0.098 x 1000 / 1 => 98.0 g
mass of solvent = 500.0 g
Therefore:
% ( w/w ) = 98.0 / 98.0 + 500.0
% (w/w ) = 98.0 / 598.0
0.163 x 100 => 16.3 %
Answer:
The organic compounds (heptane/cyclohexane) will get dissolve in Cl₂ water forming a yellow colored solution.
When NaI is added into it, the following reaction between NaI and Cl2 takes place;
Cl₂ + NaI ⇒ I₂ + NaCl
In above reaction, oxidation state of Cl is getting reduced from 0 in Cl2 to -1 in NaCl.
Therefore, Cl2 is getting reduced and acting as an oxidizing agent in the reaction. While I⁻ is getting oxidised annd acting as a reducing agent
Answer:
you would need to multiply 50 times 2 wich is 100 so i beleive its 100
Explanation:
Initial Conditions:
Volume= v1= 417 cm³
Temperature= T1 = 278 K
Final Conditions:
Temperature= T2 = 231K
Volume = v2 =?
Use the general gas equation;
P1*v1/T1 = P2*v2/T2
As, the temperature is constant;
So,
v1/T1 = v2/T2
417/278 = v2/231
v2= 346.5 cm³
