Calculate the final concentration and uncertainty when combining measured values of 5.0 g/L ± 0.5, 7.5 g/L ± 0.7, using the appropriate propagation method.
💡 Hint: Remember to apply the quadrature method correctly.
You have measurements x = 15.0 ± 0.2 and y = 3.0 ± 0.1. If you need to find the area A = x * y, what is the area and its uncertainty?
💡 Hint: Focus on how you can apply relative uncertainties in multiplications.
