Answer:
<h3>The answer is 6 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 15 g
volume = 2.5 mL
We have
We have the final answer as
<h3>6 g/mL</h3>
Hope this helps you
Answer:
C₄H₁₂
Explanation:
The empirical formula gives you your smallest whole number ratio for the elements in the compound. Find the molar mass using a periodic table. We have one carbon (12.01 g/mol) and three hydrogens (1.008 g/mol). Therefore our molar mass for the empirical formula is 12.01 + 3(1.008) = 15.034 g/mol. To find the molecular formula divide the given molar mass by the empirical formula's molar mass 60.2/15.034 = 4.004257017 = 4. This number is the amount to multiply the empirical formula by to get the molecular formula, therefore your molecular formula is C₄H₁₂

<h3>
Answer:</h3>
The higher is its frequency.
<h3>
Explanation:</h3>
- Electromagnetic waves are types of waves that do not require a material medium for transmission.
- They include radio waves, microwaves, infra-red and gamma rays among others.
- Frequency refers to the number of complete oscillations in one second while wavelength is the distance between two successive crests or trough in a transverse wave.
- The frequency of electromagnetic waves varies inversely to the wavelength.
- Electromagnetic waves with higher frequencies such as x-rays and gamma rays have lower wavelengths.
- Those with higher wavelengths, on the other hand, such as microwaves and radio waves have lower frequencies.
