I believe the answer is 4.2
Answer:
Yes
Explanation:
Yes, but almost insignificantly. The regular boiling point of water is 100 degrees celcius, adding a small handfull of salt will increase the boiling point to roughly 100.04 degrees celcius. Therefore, it is almost insignificant but still does affect it. This is mainly because salt changes the way the molecules react thus making it harder for them to change state from liquid to gas. This ultimately causes the water to get hotter before boiling actually occurs.
Answer : The formula mass of the compound in amu is, 217.62 amu
Explanation : Given,
29.2 % Copper by mass that means 29.2 grams of copper present in 100 grams of compound.
As we know that,
1 atom of copper has an atomic mass of 63.546 amu.
Now we have to determine the formula mass of the compound.
![\text{Formula mass of compound}=\frac{\text{Atomic mass of copper}}{\text{Given mass of copper}}\times \text{Mass of compound}](https://tex.z-dn.net/?f=%5Ctext%7BFormula%20mass%20of%20compound%7D%3D%5Cfrac%7B%5Ctext%7BAtomic%20mass%20of%20copper%7D%7D%7B%5Ctext%7BGiven%20mass%20of%20copper%7D%7D%5Ctimes%20%5Ctext%7BMass%20of%20compound%7D)
![\text{Formula mass of compound}=\frac{63.546amu}{29.2g}\times 100g=217.62amu](https://tex.z-dn.net/?f=%5Ctext%7BFormula%20mass%20of%20compound%7D%3D%5Cfrac%7B63.546amu%7D%7B29.2g%7D%5Ctimes%20100g%3D217.62amu)
Therefore, the formula mass of the compound in amu is, 217.62 amu
