In this lesson, we will learn how to describe methods for measuring solid and liquid densities, identifying errors, and troubleshooting mistakes.
Q1:
An irregular piece of shiny yellow metal is weighed and then submerged in a graduated cylinder partially filled with water as shown in the figure.
The dry mass of the metal piece is 57 g.
What is the density of the metal piece?
What is the metal piece most likely made of?
Q2:
The table shown lists the density of oxygen in solid, liquid, and gaseous forms.
To 1 decimal place, how many times more molecules are present in solid oxygen than in an equal volume of oxygen gas?
Q3:
The molecular formulas and densities of five B vitamins are shown in the table.
Which of these vitamins contains the most molecules per unit volume?
Which of these vitamins contains the fewest atoms per unit volume?
Which of these vitamins contains the most hydrogen atoms per unit volume?
Which of these vitamins contains the most nonhydrogen atoms per unit volume?
