Concept explainers
Interpretation:
The volume of nitrogen gas produces when 50 mL of solid nitrogen sublimes needs to be calculated given the density of solid nitrogen is 1.026 g/cm3 and nitrogen gas is 0.00125 g/cm3.
Concept introduction:
The density of a substance is the mass occupied by it per unit volume i.e.
Answer to Problem 5STP
(B) 41 L
Explanation of Solution
Given:
Density of solid nitrogen = 1.026 g/cm3
Density of nitrogen gas = 0.00125 g/cm3
Volume of solid nitrogen = 50 mL
1 mL = 1 cm3
Calculation:
Calculate the mass of solid nitrogen as follows:
Based on equation (1):
Calculate the volume of nitrogen gas produced as follows:
Mass of solid nitrogen present = Mass of nitrogen produced = 51.3 g
Thus, the volume of nitrogen gas produces when 50 mL of solid nitrogen sublimes is 41 L.
