Answer:
Explanation:
The molecular formula for Potassium Dichromate is K2Cr2O7. The SI base unit for amount of substance is the mole. 1 mole is equal to 1 moles Potassium Dichromate, or 294.1846 grams.
Note that rounding errors may occur, so always check the results.
Answer:- 
Solution:- First of all we calculate the heat absorbed or released when the solute is added to the solvent. Here the solute is LiCl and the solvent is water.
To calculate the heat absorbed or released we use the formula:
q = heat absorbed or released
m = mass of solution
s = specific heat capacity
and 
= change in temperature
mass of solution = mass of solute + mass of solvent
mass of solution = 5.00 g + 100.0 g = 105.0 g
(note:- density of pure water is 1 g per mL so the mass is same as its volume)
= 33.0 - 23.0 = 10.0 degree C
s = 
Let's plug in the values in the formula and calculate q.
q = 
q = 4389 J
To calculate the enthalpy of solution that is 
we convert q to kJ and divide by the moles of solute.
moles of solute = 
= 0.118 moles
q = 
= 4.389 kJ
= 
Since the heat is released which is also clear from the rise in temperature of the solution, the sign of enthapy of solution will be negative.
So,
I think answer should be d. Please give me brainlest I hope this helps let me know if it’s correct or not okay thanks

Answer:
0.567 g/mL
Explanation:
First, we will find the mass of the liquid. Subtract the weight of the empty cylinder from the weight of the filled cylinder
110.81 - 82.45 = 28.36
The mass of the liquid is 28.36 g.
Now, we find the density by dividing the mass by volume
28.36/50 = 0.5672
