Putting solar panels on houses is a great idea, for it provides a renewable source of energy and heat, which is the sun. It will help prevent pollution and the mass-use of non-renewable resources, such as fossil fuels, which are used and burned for energy.
Although, having solar panels, there will be some downsides. For example, solar panels can only receive energy during time where there is light from the sun, which is daylight. therefore, the solar panels will not and cannot be able to collect energy from the sun during night time. although, depending on the solar panels, some can store energy, from the sun, that can be used at night time, like as if you're charging a battery with energy from the sun for later use. one big problem is that, solar panels are not cheap and rather quite expensive, which not all homes and families can afford. although, through time, solar panels will get cheaper.
but, all in all, I believe that solar panels give a great contribution to Earth, thus I agree to the use of solar panels.

Answer:
13.92 %
Explanation:
Mass of 
= 12.5221 g
Molar mass of = 233.43 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of = 0.0536 moles
According to the given reaction,
1 mole of is formed from 1 mole of 
Thus,
0.0536 moles of is formed from 0.0536 moles of
Moles of = 0.0536 moles
Moles of sulfur in 1 mole = 1 mole
Moles of sulfur in 0.0536 mole = 0.0536 mole
Molar mass of sulfur = 32.065 g/mol
Mass = Moles * Molar mass = 0.0536 * 32.065 g = 1.7187 g
Mass of ore = 12.3430 g
Mass % = 
= 
= 13.92 %
The mass of sulfur in a sample of CaSO4 with a mass of 65.8 g is 15.50g.
<h3>How to calculate mass of an element in a compound?</h3>
According to this question, a 10.4 g sample of CaSO4 is found to contain 3.06 g of Ca and 4.89 g of O.
This means that the mass of sulfur in the 10.4g of CaSO4 is 10.4g - (3.06g + 4.89g) = 10.4g - 7.95g = 2.45g
Next, we calculate the percent ratio of each element in the compound; CaSO4.
- Ca = 3.06g/10.4g × 100 = 29.42%
- S = 2.45g/10.4g × 100 = 23.56%
- O = 4.89g/10.4g × 100 = 47.02%
According to this question, a sample of CaSO4 with a mass of 65.8 g is given. The mass of each element in this compound is as follows:
- Ca = 29.42/100 × 65.8g = 19.36g
- S = 23.56/100 × 65.8g = 15.50g
- O = 47.02/100 × 65.8g = 30.94g
Therefore, the mass of sulfur in a sample of CaSO4 with a mass of 65.8 g is 15.50g.
