1 answer:
Answer:
0.045 moles of NaOH
Explanation:
When this units are together mol/L, we talk about M, molarity.
This kind of concentration shows the relation between moles of solute which are contained in 1L of solution.
In this case, our NaOH solution is 0.30 M
M = mol/L
Then, M . L = mol
We convert volume to L → 150 mL . 1L /1000 mL = 0.150L
0.150 L . 0.30mol/L = 0.045 moles

According to one acid-base theory, a water molecule acts as an acid when the water molecule (3) donates an H+.
Answer:
0.025 g C6H12O6
Explanation:
ppm = (g solute/ g solution)* 10^6
g solute= (ppm * g solution)/ 10^6
g solute = (250 ppm * 100 g)/10^6
g solute=0.025 g C6H12O6
