1 mol = 6.022 x 10²³ atoms
In order to find how many atoms, dimly multiply the amount of moles you have by 6.022 x 10²³ or Avogadro's number.
So you have 1.75 mol CHC1₃ x (6.022x10²³) = 1.05385 x 10²⁴ atoms of CHCl₃
But now you have to round because of the rules of significant figures so you get 1.05 x 10²⁴ atoms of CHCl₃
A diatomic molecule (or a non-polar covalent molecule).
So we know that the formula to calculate molarity is:
Where M is the molarity, moles is the number of moles in the solution, and L is the volume of the solution in liters.
So we are given the molarity of the solution (5.80 M) and the volume of the solution in liters (6.5 L). So now we just need to plug these numbers in and solve for moles:
So now we know that there are 37.7 moles of lithium nitrate in the solution.
Answer:
magnesium
Explanation:
it is the only metal in the choices. everything else is on the right side of the old line that separates metals and nonmetals on the PPT. nonmetals aren't, shiny or good conductors or malleable or ductile. only metals can have those qualities. the only metal is magnesium
