Guys- my science teacher doesn't teach, he just says go on schoology ​
Free_Kalibri [48]
The relative mass of each element can be found from the periodic table (the larger number). For instance, P2O5, P = 31.0 O = 16.0, thus the formula mass (Mr) is 2(31) + 5(16) = 142 amu (atomic mass unit). I used a not really specific periodic table. Maybe your teacher is referring to open Schoology (a website where teacher can post files or announcements to students in his or her class). Sorry if i got something mistaken.

Suppose you are titrating a sulfuric acid solution of unknown concentration with a sodium hydroxide solution according to the eq
Inga [223]

Answer:

M_{acid}=0.0444M

Explanation:

Hello,

In this case, for the given reaction:

H _2 S O _4 + 2 N a O H \rightarrow 2 _H 2 O + N a _2 S O_ 4

We find a 1:2 molar ratio between the acid and the base respectively, for that reason, at the equivalence point we find:

2*n_{acid}=n_{base}

That in terms of concentrations and volumes we can compute the concentration of the acid solution:

2*M_{acid}V_{acid}=M_{base}V_{base}\\\\M_{acid}=\frac{M_{base}V_{base}}{2*V_{acid}}=\frac{0.697M*28.07mL}{2*220.1mL}\\ \\M_{acid}=0.0444M

Best regards.
