Mass = molarity x molar mass( NaNO₃) x volume
mass = 1.50 x 85.00 x 4.50
mass = 573.75 g of NaNO₃
hope this helps!
The number of energy levels to which an electron can jump depends on the amount of energy the electron possesses. Each energy level has a specific amount of energy an electron needs to have before it can be in there. So, if an electron doesn't have enough energy to be in that energy level then it won't jump to that higher level.
When you burn paper you are chemically altering it so that is the correct answer. When you do all the other choices all of the components stay the same. Just because it changes shapes doesn't mean it'll change chemically toom
Answer:
0.0250 g
Explanation:
Step 1: Determine the molar mass of Vitamin C.
The molar mass is the mass in grams corresponding to 1 mole. In order to calculate the molar mass of vitamin C (C₆H₈O₆) we need to add the molar masses of the elements that compose it.
M(C₆H₈O₆) = 6 × M(C) + 8 × M(H) + 6 × M(O)
M(C₆H₈O₆) = 6 × 12.01 g/mol + 8 × 1.01 g/mol + 6 × 16.00 g/mol
M(C₆H₈O₆) = 176.14 g/mol
Step 2: Calculate the mass corresponding to 0.000142 mol of vitamin C.
Yeas, the reaction is balanced
