It is not important whether this '200 ml of solution' is countable without or without the hydrated compounds contribution of H2C2O4.2H2O
At first find moles of this
3.78 grams H2C2O4 . 2H2O ( 1 mole cpd./126.068 grams)
= 0.02998 moles H2C2O4 . 2H2O
Since Molarity = moles of solute/Liters of solution ( 200 ml = 0.200 Liters )
Molarity = 0.02998 moles H2C2O4 . 2H2O/0.200 Liters
= 0.150 M H2C2O4.2H2O

∙ 10y ago3.78 (g H2C2O4.2H2O) / 126.068 (g.mol-1 H2C2O4.2H2O) = 0.02998 (mol H2C2O4.2H2O)
Molarity = moles of solute per Liters of solution
= 0.02998 (mol H2C2O4.2H2O) / 0.200 (Liters) = 0.150 (mol.L-1 H2C2O4.2H2O)
Answer: Molarity = 0.150 M

2.38g = 2.38/126.0658 = 0.0189mol dissolved in 200ml solution.
Molarity = 1000/200*0.0189 = 0.094M

∙ 8y agomolar mass H2C2O4x2H2O = 2+24+64+36 = 126 g/mole
moles = 2.38 g x 1mol/126 g = 0.0189 moles
molarity = 0.0189 moles/0.200 L = 0.0944 M

Molarity = moles of solute/Liters of solution Molarity = 0.202 moles KCl/7.98 Liters = 0.253 M KCl solution ================
2.431 g of h2c2o4 x 2h2o was obtained and dissolved in enough dI water to form 250.0 ml of solution what is the concentration of the resulting of h2c2o4 solution?
Molarity (concentration ) = moles of solute/Liters of solution 250.0 ml = 0.250 liters 2.431 grams H2C2O4 * 2H2O ( 1mole cpd/ 126.068 grams) = 0.01928 moles H2C2O4 * 2H2O Molarity = 0.01928 moles cpd/0.250 liters = 0.07712 Molarity
If 25.5mg of oxalic acid dihydrate are dissolved in 1.00 ml of solution what is the molarity of the resulting solution?
0.063 g of oxalic acid * (1 mol H2C204*2H2O / 126.07 g) = 0.0004997 mol H2C2O4*2H2O 0.0004997 mol H2C204 / 0.250 L = 0.001999 M of H2C2O4
What is the product of NaOH H2C2O4?
There is no chemical reaction between these products, so if you would bring them together nothing will happen.
Does the molarity of a solution decrease on raising the temperature of the solution?
If you raise a solution temperature the molarity will decrease.
What is the molarity of a solution with 5mol solute in 4.5L solution?
Molarity = moles of solute/Liters of solution Molarity = 5 moles solute/4.5 Liters of solution = 1 M solution ==========
What molarity of a solution indicate?
Molarity is an indication for concentration.
What does molarity of a solution indicate?

HP- + H2O(l) ⇌ P2-(aq) + H3O+(aq)
What is the effect on the molarity of a solution of adding more solvent to a solution?
Adding more solvent to a solution decreases the molarity of the solution. This is based on the principle that initial volume times initial molarity must be equivalent to final volume times final molarity.
