A pharmacist prepares an antiulcer medicine by mixing 286 g Na2CO3 with water, adding 150 g glycine (C2H5NO2), and stirring continuously at 40°C until a firm mass results.The pharmacist heats the mass gently until all the water has been driven away. No other chemical changes occur in this step. Compute the mass percentage of carbon in the resulting white crystalline medicine.
