Find the empirical formula of the compound containing 2.4 gram of carbon, 6.4 gram of oxygen and 0.2 gram of hydrogen

Usimov [2.4K]

Answer:

Empirical formula= COOH

Step-by-step explanation:

Molecular mass of the elements

Carbon= 12

Oxygen= 16

Hydrogen= 1

We divide the elements each with their molecular formula

Carbon= 2.4/12

Carbon= 0.2

Oxygen= 6.4/16

Oxygen= 0.4

Hydrogen= 0.2/1

Hydrogen= 0.2

Now we divide with the smallest result which is 0.2

Carbon= 0.2/0.2

Carbon = 1

Oxygen= 0.4/0.2

Oxygen= 2

Hydrogen= 0.2/0.2

Hydrogen= 1

So we have

Carbon 1, oxygen 2, hydrogen 1

Empirical formula= COOH

If a bank account doubles in size every 5 years, then by what percent does it grow after only 3 years? Round to the nearest tent

mr Goodwill [35]

Answer:

Step-by-step explanation:

Alright, let get started.

Suppose the initial deposit in account = x

After five years, this accounts get doubled means = 2x

Means in 5 years , the growth = $2x-x = x$

So, in 1 year, the growth will be = $\frac{x}{5}$

So, in 3 years, the growth will be = $\frac{x}{5}*3=\frac{3x}{5}$

So percent grwoth will be = $\frac{\frac{3x}{5}}{x}*100 = 60$

Hence percentage growth is 60 %. : Answer

Hope it will help :)
