How many moles in a litte?​

Mathematics
1 answer:

the number of moles in a liter is 0. 045 moles

<h3>What is mole?</h3>

Mole, in chemistry, is known as a standard scientific unit used  for measuring large quantities or amounts of very small entities such as atoms, molecules, or other specified particles.

It is important to note that the number of units in a mole is also called its Avogadro’s number

The basis for the conversion of moles to liters is

1mol = 22.4Liter

Hence,

If 1 mol = 22. 4Liter

Then x mol = 1Liter

Cross multiply

x × 22. 4 = 1 × 1

22. 4x = 1

Divide through by 22.4

x = 1/ 22. 4

x = 0. 045 moles

Thus, the number of moles in a liter is 0. 045 moles

Paul has $30,000 to invest. His intent is to earn 15% interest on his investment. He can invest part of his money at 8% interest
jeka94

Answer:

Amount invested at 8% is $9000 and amount invested at 18% is $21000.

Step-by-step explanation:

Let amount invested at 8% be x.

Let amount invested at 18% be y.

We get the 1st equation as:

x+y=30000       ........(1)

We get the second equation as:

0.08x+0.18(y)=0.15\times30000

=> 0.08x+0.18y=4500

or getting rid of the decimal by multiplying by 100 on both sides.

8x+18y=450000          ........(2)

Multiplying (1) by 8 and subtracting from (2) we get

10y=210000  

So, y = 21000

And x+21000=30000

x = 30000-21000

So, x = 9000

Therefore, amount invested at 8% is $9000 and amount invested at 18% is $21000.
