There are 2 moles of NA2SO4 present in 284.078 grams of NA2SO4. Why? Well, we already know here that there are 284.078 grams of NA2SO4. To find how many moles are present in this compound, we would have to divide these grams by the molar mass of the compound. When we go to the periodic table of elements, we will find that there are two moles sodium (which represents 45.98 grams), one mole sulfur (which represents 32.06 grams), and four moles oxygen (which represents 64 grams). When combining these, we would get one mole of sodium sulfate which is representative of 142.04 grams total. That is our molar mass. Now that we have the molar mass, we can go back and divide. 284.078 divided by 142.04 is equal to about 1.99999, and that rounds up to 2 moles. Hence, there are 2 moles of NA2SO4 present in 284.078 grams of NA2SO4.
Your final answer: A is your answer.
Answer:
D) saturated fat
Explanation:
Saturated fat -
It is a form of fat , where saturation is present , i.e. , presence of single bonds , it is a type of very unhealthy fat .
Butter , red meat , coconut oils and palm are rich in saturated fat , and are mostly in solid state at room temperature .
These fats often tends to be collected in the walls of arteries , and , can act as a restriction to the flow of blood .
Hence , the correct option for the given information of the question is saturated fat .
I think the answer is C I think that bc I added 3 and the 2 which made it H5 and than multipled the 3 and the 2 which made it C6 than Cl
