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
The answer is c.......................................
Acetylsalicylic acid (ASA) or commonly known as aspirin is used as pain reliever, treatment for fever and inflammation. The type of bond that aspirin have is covalent bond. Covalent bond is when atoms share their electrons. Aspirin is made up of carbon, hydrogen and oxygen with a formula of C9H8O4.
The answer to the question is true.
