Hey there!
Mass of NaCl = 4.78 g
Molar mass of NaCl = 58.44 g/mol
Volume of solution = 12.34 mL
Number of moles:
n = mass of solute / molar mass
n = 4.78 / 58.44
n = 0.08179 moles of NaCl
Volume in liters:
12.34 mL / 1000 => 0.01234 L
Therefore:
Molarity = number of moles / Volume ( L )
Molarity = 0.08179 / 0.01234
Molarity = 6.62 M
Hope that thelps!
The reactants and products involved in the chemical reaction are written on the left and right hand side of the equation, respectively. Thus, the reactants are SO3(g) and H2O(l). The product is H2SO4(aq). This reaction is an example of synthesis wherein two reactant combine to form one product.
An increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.
