What is the concentration of a 0.750 l solution that contains 52.0 g of glucose (c6h12o6)?
vodka [1.7K]
Concentration of Solutions is oftenly expressed in Molarity. Molarity is the number of moles of solute dissolved per volume of solution.

                             Molarity  =  Moles / Volume
As,
      Moles  =  Mass / M.mass
So,
                             Molarity  =  Mass / M.mass × Volume   ---- (1)

Data Given;
                   Volume  =  0.750 L

                   Mass  =  52 g

                   M.mass  =  180 g/mol

Putting Values in eq.1,

                     Molarity  =  52 g ÷ (180 g.mol⁻¹ × 0.750 L)

                     Molarity  =  0.385 mol.L⁻¹

How many moles are in 91.5 grams of Helium?
konstantin123 [22]

In order to find the number of moles with a given mass of Helium, we need to use its molar mass, which is 4.0026g/mol, therefore we will have:

4.0026g = 1 mol of Helium

91.5g = x moles of Helium

x = 22.86 moles of Helium in 91.5 grams

Wine has a pH of 3, which means it is __________ times more acidic than tomatoes, which have a pH of 4.
Natasha2012 [34]

Answer:

10

Explanation:

pH is defined as the negative logarithm of the concentration of hydrogen ions.

Thus,  

pH = - log [H⁺]

Thus, from the formula, more the concentration of the hydrogen ions or more the acidic the solution is, the less is the pH value of the solution.

Thus, solution with pH = 3 will be more acidic than solution with pH =4  

Thus, concentration of the [H⁺] when pH =3

3 = - log [H⁺]

[H⁺] = 10⁻³ M

For pH = 4, [H⁺] = 10⁻⁴ M

<u>hence, pH = 3 is 10 times more acidic than pH = 4</u>
