Mass= number of moles multiply Mass of one mole
= 24.3 multiplied by 4
= 96.2
Answer:
frequency of light = 
Explanation:
we know that relation between frequency and wavelength of light is
frequency × wavelength = speed of light.
therefore frequency = 
= 
=
Answer:
q = 38,5 kJ
Explanation:
In its melting point, at 0°C, water is liquid. The boiling point of water is 100°C. It is possible to estimate the heat you required to raise the temperature of water from 0°C to 100°C using:
q = C×m×ΔT
Where C is specific heat of water (4,184J/g°C), m is mass of water (92,0g) and ΔT is change in temperature (100°C-0°C = 100°C)
Replacing:
q = 4,184J/g°C×92,0g×100°C
q = 38493 J, in kilojoules:
<em>q = 38,5 kJ</em>

The number of values greater than or equal to 8 is mathematically given as
x = 27
This is further explained below.
<h3>What is a data set?</h3>
Generally, Simply put, data sets are groups of information. When dealing with tabular information, a data set is analogous to one or more database tables, where each column represents a different variable and each row represents a separate record.
In conclusion, the total amount of numbers that are either more than or equal to 8
Data value 8 is only exceeded by 9, 10, 11, and 12.
- 8 occurs 4 times
- 9 occurs 6 times
- 10 occurs 8 times
- 11 occurs 4 times
- 12 occurs 5 times
Hence
x= 4+6+8+4+5
x = 27
