Answer:
Explanation:
We are given the mass, specific heat, and temperature, so we must use this formula for heat energy.
The mass is 5 grams, the specific heat capacity is 0.14 Joules per gram degree Celsius. Let's find the change in temperature.
- ΔT= final temperature - initial temperature
- ΔT= 95°C - 15°C = 80°C
We know the variables and can substitute them into the formula.
Multiply the first numbers. The grams will cancel.
Multiply again. This time the degrees Celsius cancel.
56 Joules of heat are needed.
One that has a constant temperature, that's even throughout the entire object. You didn't list down the choices, but whatever that fits this criteria is the correct answer. Maybe, if you comment down the choices; I'll tell you the correct ones.
To determine the number of atoms of a substance given its number of mols, multiply number of moles with the Avogadro's number which is approximately equal to 6.022x10^23.
To answer the problem above, multiply 3.50 mols with <span>6.022x10^23. This gives a product of 2.1077x10^24.
Thus, there are </span><span>2.1077x10^24 atoms of sulfur in 3.50 mols of sulfur. </span>
