Could you tell me how to solve this using the dilution formula? The correct answer is 3.903g and I just need to know why that is.
A weighted sample of Na,coz (FM 105.99 g/mol) was dissolved to make 250.0 mL aqueous solution. A 25.00-ml portion of that solution is first pipetted and then diluted by adding 475.0 mL of water. Assume the volumes are additive. The concentration of the diluted solution is 7.365 mm. What is the mass of the sodium carbonate original sample (in grams)? 0.7365 3.9038 1.2375 0.14735 Question 3 (1 point)
