The density of a pure substance is its mass per unit volume. The density of cresol has been measured to be 1024 g/L . Calculate

Ierofanga [76]

Answer: The mass of 405 ml of cresol is 415 grams

Explanation:

Density is defined as the mass contained per unit volume.

$Density=\frac{mass}{volume}$

Given : Density of cresol = 1024 g/L

Volume of cresol = 405 ml = 0.405 L ( 1L=1000ml)

Putting in the values we get:

$1024g/L=\frac{mass}{0.405L}$

$mass=1024g/L\times 0.405L=415g$

Thus mass of 405 ml of cresol is 415 grams

Which groups of the periodic table want to gain electrons? What kind(s) of elements are these groups

lukranit [14]

Answer:

Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.
