Elements and compounds are both examples of pure substances. around the world. What mass of sodium reacted? Which capital is farther north Salt Lake City Utah or Carson City Nevada? Answer: A homogeneous mixture is a mixture having a uniform composition throughout the mixture. b. Other salts like bromides and gypsum are more soluble than carbonates but still not as soluble as sodium chloride or potassium and magnesium-based salts. If its composition is uniform throughout, it is a homogeneous mixture. You will notice 3 grams of salt does not contain 3 grams of sodium, nor is half the mass of salt from sodium, so 3 grams of salt does not contain 1.5 grams of sodium: Then the amount of sodium in 3 grams of salt = 39.3% x 3 = 1.179 g or about 1200 mg. An easy way to calculate the amount of sodium in salt is to realize 39.3% of the amount of salt comes from sodium. If the water is warm or even hot, it will easily be able to dissolve the salt into it and form a homogeneous mixture. The components in a homogeneous mixture are well mixed. Alcohol: Alcohol exists in pure form it is not said to be a mixture. Saltwater acts as if it were a single substance even though it contains two substancessalt and water. Alloys are made when two or more metals are mixed together. Molecules include hydrogen (H2), oxygen (O2), nitrogen (N2), chlorine (Cl2) etc.
