What happened before the Big Bang?
Answer: C = 0.014M
Explanation:
From n= m/M= CV
m =43.5 M= 148, V=850ml
43.5/148= C× 0.85
C= 0.35M
Applying dilution formula
C1V1=C2V2
C1= 0.35, V1= 25ml, C2=?, V2= 600ml
0.35× 25 = C2× 600
C2= 0.014M
A base in water will form hydroxide ions. This is because bases are AOH while acids are AH+. I hope this helps!
P = mv, where p is momentum, m is mass in kg and v is velocity in m/s
