Answer:
2
Explanation:
The total number of atoms in silver sulfate Ag2SO4 is 2
Answer:
The answer to your question is 6.0M, I know that you said it was not the answer, but it is. Check the significant figures.
Explanation:
Data
Molarity = ?
volume of HCl = 50 ml
volume of NaOH = 4 M
volume = 75 ml
Balanced chemical reaction
HCl + NaOH ⇒ NaCl + H₂O
Process
1.- Calculate the moles of NaOH
Molarity = moles/volume
moles = Molarity x volume
moles = 4 x 0.075
moles = 0.3 of NaOH
2.- Use proportions to calculate the moles of HCl
1 mol of NaOH ----------------- 1 mol of HCl
0.3 moles of NaOH ---------- x
x = (0.3 x 1)/1
x = 0.3 moles of HCl
3.- Calculate the molarity of HCl
Molarity = 0.3/0.05
Molarity = 6.0 M
