A36 gram sample contains 28 grams of fe and 8 grams of oxygen. determine the percent composition for each of the elements.

The sample contains both Fe and oxygen

The mass of the sample is 36 g

28 g are Fe and 8 g are O

So to find the percent composition we can calculate using the following formula

Percent composition of the element = mass of the element / mass of the sample x 100%

Percent composition of Fe = 28 g / 36 g x 100 % = 77.8%

Percent composition of O = 8 g / 36 g x 100 % = 22.2%

The percentage composition for each of the elements is

Fe =77.8 % oxygen= 22.2%

calculation

% composition = mass of the element/total mass x100

total mass = 36g

The % composition of Fe = 28/36 x100 = 77.8%

The % composition of oxygen = 8/36 x100 = 22.2%

answer: e.   sour taste

explanation: acids are those substances which dissociates in water to give ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. acids are sour in taste. example: hcl

bases are those substances which dissociates in water to give ions or accepts ions. as they dissociate to give ions, they act as electrolytes and thus are electrically conductive. bases are bitter in taste. bases are slippery in nature.
