Answer:
12 g
Explanation:
We want to prepare 1 L of a 0.15 M NaOH solution. The moles of NaOH required are:
0.15 mol/L × 1 L = 0.15 mol
The molar mass of NaOH is 40.00 g/mol. The mass corresponding to 0.15 mol is:
0.15 mol × (40.00 g/mol) = 6.0 g
The starting solution is 50% by weight. The mass of solution that contains 6.0 g of NaOH is:
6.0 g NaOH × (100 g solution/50 g NaOH) = 12 g solution
Answer:
i think b is the answer hope this helps:))
Answer:
Conociendo el volumen de solución, masa de soluto y su masa molar, es posible determinar: B) Concentración molar
La molaridad es la relación entre el número de moles de soluto y los litros de solución. Más:
M = No moles de solución de soluto / volumen (L)
Y a su vez los moles de soluto se encuentran por:
No moles de soluto = masa soluto / masa molar soluto
Answer: An acid-base reaction is the transfer of a proton from a proton donor ... The reaction between a Brønsted-Lowry acid and water is called acid ionization.
