How many grams of Na_(2)CO_(3) should be dissolved in 250 g of water t – InterviewSolution

1.	How many grams of Na_(2)CO_(3) should be dissolved in 250 g of water to prepare 0.1 m solution?
Answer» Solution :`"0.1 m solution MEANS 0.1 mole of "Na_(2)CO_(3)" is present in 1000 g of WATER"` `therefore " 250 g of water should contain "Na_(2)CO_(3)=(0.1)/(4)"Mole = 0.025 mole "=0.025xx106 g = 2.65 g`
