Mg = 24.3
Cl = 35.5
24.3 + 35.5 x 2 = 95.3 ~ 95.21 ( all periodic tabes have different accuracies)
Let me know if you have any questions and please give brainliest if you like my answer:)
Moles of solute for both a and b are the same = 1 mol
<h3>Further explanation</h3>
Given
a 500 cm³ of solution, of concentration 2 mol/dm³
b 2 litres of solution, of concentration 0.5 mol/dm³
Required
moles of solute
Solution
Molarity shows the number of moles of solute in every 1 liter of solution or mmol in each ml of solution
Can be formulated :
a.
V = 500 cm³ = 0.5 L
M = 2 mol/L
n=moles = M x V
n = 2 mol/L x 0.5 L
n = 1 mol
b.
V = 2 L
M = 0.5 mol/L
n=moles = M x V
n = 0.5 mol/L x 2 L
n = 1 mol
4. The particles found outside the nucleus are the electrons.
Protons are positively charged, electrons are negatively charged, and Neutrons have no charge or are in fact "neutral". Protons and Neutrons are located in the nucleus of an atom and are most of the atoms mass. Electrons have an extremely minute mass even compared to Protons and Neutrons
