The teacher said the volume of the liquid was 500 mL when measured a student found it was 499.7 mL what is the students percent error

Explanation:

The percentage error of a certain measurement can be found by using the formula

From the question

error = 500 - 499.7 = 0.3

actual volume = 500 mL

We have

We have the final answer as

Hope this helps you

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)
