The units used to measure specific heat capacity is Joules per kilogram per Kelvin.
<h3>
What is specific heat capacity?</h3>
It is the amount of heat absorbed per kilogram of material when the temperature rises by 1 Kelvin.
Specific heat capacity C is the Joules of energy in form of heat per kilogram per Kelvin temperature. The units represented by
C = ___ J/kg.K
Thus, the units used to measure specific heat capacity is Joules per kilogram per Kelvin.

Answer:
D
Explanation:
Its the only answer that actually makes sense and i got it right on the quiz.
Hello @Lucysrv18,
How are you doing? In this case, we know that Electromagnetic waves that are visible to the human eye is neither made up of two electromagnetic waves nor three. Therefore B and C is incorrect.
These electromagnetic waves are divided and they are our final two options. For sure, i can say that the wavelengths in a visible electromagnetic wave are not divided into nine, but instead it is divided into 7.
The answer to your question is A.
Thank you,
Darian D.
Since the number of moles of a substance is the mass divided by the molar mass of the substance, we can just simply multiply the molar mass of magnesium chloride by the number of moles, which is 4.40 in this case.
To find the molar mass, refer to the periodic table for the relative atomic mass of Mg and Cl and add them together. Since there’s 2 chloride ions in MgCl2, double the relative atomic mass of Cl when adding.
24.31 + 35.45x2
=95.21
Now just multiply 95.21 to 4.40mol, which you’ll get 418.9g (corrected to 3 significant figures)
