Write the equation for the reaction and balance it. In this case the equation is: 2NaOH + H2SO4 → Na2SO4 + 2H2O
Convert the given amount to moles. Molarity, “M” is moles per liter. The given amount is 25 ml of 1.2 M H2SO4. Since Molarity uses Liters, the volume must be converted from ml to L.
Use the mole ratio in this case 2 moles of NaOH to ! mole of H2SO4
Convert the moles to the required units. In this case the required units are grams. The formula weight in grams er mole.
25 ml H2SO4 * 1L/1000 ml * 1.2 Moles/L * 2 moles NaOH/1 mole H2SO4 * 40 g NaOH/ 1 Mole NaOH
Perform these calculations and you have the answer! Timothy, When doing homework, the answer is NOT the important thing, the METHOD is! These 4 steps, combined with required changes in units will sove ANY stoichiometric problem easily.
When cohesive force is stronger than the adhesive force: concave up meniscus, water forms droplets on surface
Hey :)
In a parallel circuit, a different amount of current flows through each parallel branch of the circuit.
In the series circuit, different voltage exists across each component in the circuit.
Whereas in the parallel circuit, the same voltage exists across the multiple components in the circuit.
Hope this helps :)
