Answer:
300 mL
Explanation:
the unit formula of calcium phosphate is Ca3(PO4)2
molar mass of Ca3(PO4)2 = (3×40 + 2×31 + 8×16) g/mol = 310 g/mol
n = m/M = 35 g/(310 g/mol)
c = n/V
V = n/c = [35 g/(310 g/mol)]/0.375 mol/L
V = 0.30 L = 300 mL
Answer: A) A Visual representation of Information
Explanation:
Look up the definition of a diagram, it usually defines as what you would think. Example: If I drew a person and I wanted to represent who they were, that would be a diagram
Animal breeding is the process of selective mating of animals with desirable genetic traits, to maintain these traits in future generations.
Something like that wouldn't dissolve in oil
Answer: The volume of 0.235 M 
needed to titrate 40.0 mL of 0.0500 M 
is 8.51 ml
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is
We are given:
Putting values in above equation, we get:
Thus volume of 0.235 M needed to titrate 40.0 mL of 0.0500 M is 8.51 ml
