Answer:
Frequency = 1.25 ×10¹³ Hz
Explanation:
Given data:
Wavelength of light = 24.0 μm (2.4 ×10⁻⁵ m)
Frequency = ?
Solution:
Formula:
Speed of light = wavelength × frequency
Speed of light /wavelength = frequency
Frequency = 3×10⁸ m /s /2.4 ×10⁻⁵m
Frequency = 1.25 ×10¹³ s⁻¹
s⁻¹ = Hz
Frequency = 1.25 ×10¹³ Hz
Answer:
6 oxygen atoms
Explanation:
Step 1: Given data
Number of dinitrogen monoxide molecules (N₂O): 6
Number of oxygen atoms (O): ?
Step 2: Calculate the appropriate ratio
The ratio of dinitrogen monoxide molecules to oxygen atoms is 1:1.
Step 3: Use the ratio to calculate the number of oxygen atoms
6 molecule N₂O × (1 atom O/1 molecule N₂O): 6 atom O
Answer:
.....false
Explanation:
the particles in the air are packed apart whereas the particles in steel are closely packed and sound travel faster in solids than in gasses..
Answer:
Approximately 53.3 %.
Explanation:
Molar mass of C2H4O2
= 2 * 12.011 + 4 * 1.008 + 2 * 15.999
= 60.052
% oxygen = (31.998* 100) / 60.052 = 53.28 %
