Answer:
O volume of the solution
Explanation:
Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.
Formula:
Molarity = number of moles of solute / volume of solution in L
For example:
if we dissolve the 1 mole of NaCl to make the solution of volume 2 L. The molarity of solution is,
M = 1 mol / 2 L
M = 0.5 M
The answer is D
FeCl3 + 3 NH4OH → Fe(OH)3 + 3 NH4Cl
Explanation:
Sulfur has 6 valence electron
Valence electron shows group( in column)
The specific heat is the amount of heat per unit mass required to raise the temperature to 1 degree Celsius. (This is from google)
