How many moles of K2O are present in 40.0 mL of a 0.3 M K2O solution? I also need the formula, data, and answer.
(0.3 mol/1L)*(1L/1000mL)*(40.0mL) = 0.012mol K2O
To find the number of moles of K2O, we need to use the formula:
moles = concentration (M) × volume (L)
Given:
Concentration of K2O solution = 0.3 M
Volume of K2O solution = 40.0 mL = 0.04 L
Using the formula, we can calculate the number of moles of K2O:
moles = 0.3 M × 0.04 L
moles = 0.012 moles
Therefore, there are 0.012 moles of K2O present in 40.0 mL of a 0.3 M K2O solution.
