Concept explainers
Interpretation:
Whether mass of an object can be predicted just by looking at it or not must be explained.
Concept introduction:
Mass of an object depends on the density of the matter. Greater the density higher is the mass stored in the matter in small volume.
Answer to Problem 4E
Mass of an object can’t be predicted just by looking at it.
Explanation of Solution
Different matters have different densities. So, a matter with higher density must have higher mass if volumes are same. For example, if a very small piece of gold is taken and similar piece of aluminium is taken, their masses will be different. Piece of gold will have higher mass due to possessing higher density.
Thus, mass can’t be predicted by looking at the matter.

A chlorine analysis of the substance indicates that it contains 83.47% chlorine by mass. What element is X and what is the formula of this compound? (Hint: to identify an element or compound, identify its molar mass. Remember that Molar Mass = (grams A)/(moles A). Solve for each individually and then divide them to find molar mass.)arrow_forward1. When hydrogen sulfide (H2S, MM = 34.08 g/mol) gas is bubbled into a solution of sodium hydroxide (NaOH, 40.00 g/mol), sodium sulfide (Na2S, 78.04 g/mol) and water (18.02 g/mol) are produced according to the balanced chemical equation shown below?
