Answer:
1.332 Molar is the molarity of the glucose solution.
Explanation:
Molarity of the solution is the moles of compound in 1 Liter solutions.
Mass of glucose = 60.00 g
Molar mass of glucose = 180.2 g/mol
Volume of the solution = V = 250.0 mL = 0.250 L
(1 mL = 0.001 L)
1.332 Molar is the molarity of the glucose solution.
Answer:
Magnesium has 2 valence electrons.
Explanation:
The atomic number of magnesium is 12. This means that it has 12 protons and 12 electrons. The first electron shell can hold 2 electrons, the second can hold 8, so the third will have 2 electrons. The outermost shell of the atom has two electrons. Therefore, magnesium has 2 valence electrons.
