The answer is C. Assume specific heat to be 4.18 J/g/C
C) 3 Moles
This is because of the molecular structure shown in the image
Answer:
7
Explanation:
Na2 SO4 is the chemical identity. You can count the number of atoms just by looking
If 1mole ------------- is ---------------- 6.02*10²³
than 0.25mole ----- is ---------------- x
x = [0.25mole*6.02*10²³]/1mole = <u>1,505*10²³</u>
