What is the molarity of 100 g of HCI in 0.75L of solution?

3.656881401M

Explanation:

mass=100g

Volume in liters=0.75L

Molecular mass of HCL=36.46094

Number of moles=mass ➗ molecular mass

Number of moles=100 ➗ 36.46094

Number of moles=2.74266105

Molarity=number of moles ➗ volume in liters

Molarity=2.74266105 ➗ 0.75

Molarity=3.656881401M

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.
