Assuming the weight of oxalic acid dehydrate H2C2O4.2H2O is 126.07g what rate of oxalic acid dehydrate must be measuredto prepare 1litre of 0.1M solution.

Answer 1

0.791g of oxalic acid dehydrate must be measured to prepare 1 litre of 0.1M solution.

Calculation:

1 litre = 1000 mL

1 mole of oxalic acid dehydrate = 126.07g

1 mole of oxalic acid dehydrate = 1000 mL of 0.1M solution

Therefore, 0.126g of oxalic acid dehydrate = 1000 mL of 0.1M solution

Therefore, 0.791g of oxalic acid dehydrate = 1000 mL of 0.1M solution
