Mass number is the total number of Protons and Neutrons. Simply subtract 85 from 210. 210-85=125 neutrons
Explanation:
Given :
Amount of solute - sucrose (C12H22O11) = 41 g
Amount of solvent -soda = 355-mL
Molarity of the solution with respect to sucrose= ?
Molarity(M) is a unit of concentration measuring the number of moles of a solute per liter of solution. The SI unit of molarity is mol/L.
Formula to find the molarity of solution :
Molarity =
Amount of solvent is given in mL, let’s convert to L :
1 L = 1000 mL
Therefore, 355 mL in L will be :
= 0.355 L
We have the amount of solute in g, let’s calculate the number of moles first :
Number of moles (n) =
Molar mass of C12H22O11 = 342.29 g/mol.
Therefore, n =
= 0.119 moles.
Answer:
I think it's light production, color change (new/different), gas production (bubbles/fizzing - not boiling), precipitate, and temperature change
Answer:
A spectator ion is an ion that does not participate in a chemical reaction and is found in a solution before and after a reaction.
