Data Given:
                  Mass of H₂C₂O₂.2H₂<span>O  =  2.38 g

                  M.mass of </span>H₂C₂O₂.2H₂O  =  126 g/mol

                  Volume  =  300 ml  =  0.3 dm³

Solution:
             Molarity is given as,
 
                               Molarity  =  Moles / Vol. of Sol.
Or,
                               Molarity  =  (Mass / M.mass) × (1 / Vol)
Putting Values,
                               Molarity  =  ( 2.38 g ÷ 126 g/mol ) × ( 1 ÷ 0.3 dm³ )

                               Molarity  =  0.063 mol/dm³

How would an apple, potato, and onion all taste the same?
Firlakuza [10]

Answer:

If you were to plug your nose, it would block out more than 80% of taste, causing all three items to have no taste- therefore making them taste the same.

Calculate the mass, in grams, of cucl2 (mw = 134.452 g/mol) required to prepare 250.0 ml of a 6.11 % w/v cu2 (mw = 63.546 g/mol)
Sever21 [200]

6.11% w/v of Cu2+ implies that 6.11 g of Cu2+ is present in 100 ml of the solution

therefore,  250 ml of the solution would have: 250 ml * 6.11 g/100 ml = 15.275 g

# moles of Cu2+ = 15.275 g/63.546 g mole-1 = 0.2404 moles

1 mole of CuCl2 contain 1 mole of Cu2+ ion

Hence, 0.2404 moles of Cu2+ would correspond to 0.2404 moles of CuCl2

Molar mass of CuCl2 = 134.452 g/mole

The mass of CuCl2 required = 0.2404 moles * 134.452 g/mole = 32.32 grams
