Ok and? What happened? Where is the question
1. Pipette, measuring cylinder
Atomic Radius: Br
Ionization Energy: Sc (not sure about this one, couldn’t find it in the periodic table)
Electronegativity: N
Reason: Found electronegativity and atomic radius in my periodic table, wasn’t sure about ionization energy, so i hope i guessed right
Answer:
13.2 g Na2CO3
Explanation:
Convert 10.0 g NaOH to mol.
10.0 g x 1 mol/39.997 g = 0.250 mol
Use mol ration given by the equation: 2 mol NaOH to 1 mol Na2CO3
0.250 mol NaOH x 1 mol Na2CO3/2 mol NaOH = 0.125 mol Na2CO3
Finally, convert the moles of Na2CO3 to grams.
0.125 mol Na2CO3 x 105.99 g/1 mol = 13.2 g
