What is the molarity of a 30.0 mL solution with 1.8 moles?

60M

Explanation:

The following were obtained from the question:

Volume = 30mL

We need to convert 30mL to L as shown below

1000mL = 1 L

Therefore, 30mL = = 30/1000 = 0.03L

Mole = 1.8 mole

Molarity =?

Molarity = mole/Volume

Molarity = 1.8/0.03

Molarity = 60 M

The molality is 60M

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
