Option A. is the best answer
I dont get what you are asking is there answers?
Answer:
Yes, this answer is correct.
Explanation:
Absolute zero is -273.15 degrees celsius
T= Tc+273.15
T is the kelvin temperature
Tc is the temperature in degrees celsius
substitute;
T= -273.15 + 273.15
T=0 K

Answer:
Number of moles = 0.92 mol
Explanation:
Given data:
Mass of CaSO₄ = 125 g
Number of moles of CaSO₄ = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of CaSO₄:
Molar mass of CaSO₄ = 40 + 32+ 16×4
Molar mass of CaSO₄ = 40 + 32+ 64
Molar mass of CaSO₄ = 136 g/mol
Number of moles:
Number of moles = mass/ molar mass
Number of moles = 125 g/ 136 g/mol
Number of moles = 0.92 mol
