Answer 3

A luminous intensity

Question 4

What is Avogadros constant?

Answer 4

1 mole= 6.02 x 1023 particles

Question 5

What does molarity mean?

Answer 5

Molar concentration of a compound in solution

Question 6

What does 1 mole/L mean?

Answer 6

That the solution contains 1 mole of the compound per 1L of the solution

Question 7

What does molar weigh mean?

Answer 7

The weight of 1 mole of a compound. Molar weight is normally expressed in g/mole

Question 8

How do you make 1L of 1M solution?

Answer 8

Weigh 1 mole of the compound , dissolve it in a solvent and adjust the volume to 1L

Question 9

How many moles if 1M per 1L?

Answer 9

1 mole

Question 10

How many mole is in 1mM- 1 mmole per 1L?

Answer 10

10-3 mole

Question 11

How many mole in 1 micro molar per 1L ?

Answer 11

10-6 mole

Question 12

How many mole on 1nmole per 1L?

Answer 12

10-9 mole

Question 13

How many mole in 1 pmole per 1L?

Answer 13

10-12 mole

Question 14

What could concentrations normally be expressed in?

Answer 14

Mg/ml,M,%

Question 15

What does a 1% solution mean?

Answer 15

1% mean 1g of the compound + 99g of the solvent so total weight of solution is 100g

Question 16

What is dilution?

Answer 16

Is a reduction of a solution concentration in accordance with dilution factor, which shows the level of dilution (how much you have diluted your solution)
