First of all, you need to convert mL to L; 120mL = 0.12L, 300mL = 0.3L.
n (moles of carbonic acid) = C (concentration) x V (volume)
n = 0.15M (0.15 mol L-1) x 0.12L
n = 0.018 mol
C (conc. of NaOH) = 0.018 mol x 2 moles (because there’s 2x NaOH) = 0.036 mol
C = n / V
C = 0.036 mol / 0.3 L
C = 0.12 mol L-1
Answer:
Mathematics is used in Physical Science to calculate the measurements of objects and their characteristics, as well as to show the relationship between different functions and properties. Arithmetic, algebra and advanced mathematics may be used.
Explanation:
salute vs the solvent a solvent is what a salute gets dissolved in
in this case the salute is the chocolate and the solvent is the water
It helps shape and create the study of electromagnetism
