Answer:
18.2784 g
Explanation:
First we <u>convert 180 lb to kg</u>:
- 180 lb * 0.453 kg / lb = 81.6 kg
Now we <u>calculate the mass of antibiotic taken in one day</u>:
- 8.0 mg/kg * 81.6 kg = 652.8 mg
Given that it is taken twice daily, <em>in one day the person would take (652.8 * 2) 1305.6 mg</em>. In grams that mass would be:
- 1305.6 mg / 1000 = 1.3056 g
Finally we multiply those 1.3056 daily grams by the 14 days in two weeks:
- (1.3056 g) * 14 = 18.2784 g
Answer:
Mass cannot be created or destroyed
Explanation:
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Answer to this question is absorbed
Let's see the balanced equation
![\\ \rm\Rrightarrow 2Ca+O_2\longrightarrow 2CaO](https://tex.z-dn.net/?f=%5C%5C%20%5Crm%5CRrightarrow%202Ca%2BO_2%5Clongrightarrow%202CaO)
Hence
As moles are equal given
- Ca should be the limiting reagent
- 2mol Ca produces 2 mol CaO
- 3mol Ca produces 3mol CaO
The chemical formula of benzene is C6H6, so it consists of six carbon atoms and six hydrogen atoms. Benzene is an aromatic hydrocarbon, which is a chemical compound consisting of carbon and hydrogen atoms with alternating double bonds forming a ring.
