Guys- my science teacher doesn't teach, he just says go on schoology

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.

A compound is determined to have the empirical formula C2OH4. If the molar mass of the compound is 132 g/mol, determine the mole

8_murik_8 [283]

Answer: The molecular formula will be $C_6O_3H_{12}$

Explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Empirical weight of $C_2OH_{4}$ is $12\times 2+16\times 1+1\times 4=44g$

Molecular mass of compound is = 132 g

Now we have to calculate the molecular formula.

$n=\frac{\text{Molecular weight}}{\text{Equivalent weight}}=\frac{132}{44}=3$

The molecular formula will be= $3\times C_2OH_4=C_6O_3H_{12}$

Answer:

See detailed explanation.

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to tell that neutralization reactions are usually double replacement reactions whereby an acid reacts with a base, commonly a hydroxide, in order to obtain a salt product and water.

They are called neutralization because they look for the neutral pH, 7, as a result of the reaction. Thus, the aforementioned can be depicted by bearing to mind the example of the neutralization of hydrochloric acid with sodium hydroxide to yield sodium chloride (salt) and water:

$HCl+NaOH\rightarrow NaCl+H_2O$
