Answer:
13.1743
Explanation:
1 grams Calcium to mol = 0.02495 mol
Answer:
1. Protons
2. Electrons
3. Neutrons
4. Protons and neutrons
5. Electrons
Explanation:
The protons are the only positive sub-atomic particles and the have a charge of +1.
The Electrons are the only negative subatomic particles and they have a charge of -1
Neutrons do not have any charge but they have the same mass as the protons
The nucleus of an atom is where most of the atomic masses are concentrated and it houses the neutrons and protons
The electrons reside outside the nucleus and they have a much more lesser mass compared to the neutrons and protons
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
