Molar mass Argon = <span>39.948 g/mol
number of moles = mass solute / molar mass
n = 150 / </span><span>39.948
n = 3.7548 moles
hope this helps!</span>
When the temperature increases the atoms gain energy and the substance changes into a gas state.
The is the opposite when the temperature decreases and the liquid becomes solid ( in this case ice).
Answer:
0.1186mol Hg
Explanation:
To calculate the number of moles using the mass we divide the mass by the molar mass.
23.79g ÷ 200.59g/mol = 0.1186mol Hg
You always adjust numbers and it will be before the element
so you Neva add or change a subscript
