Answer:
Explanation:
Hello!
In this case, since the energy involved during a heating process is shown below:
Whereas the specific heat of water is 4.184 J/(g°C), we can compute the heated mass of water by the addition of 11.9 kJ (11900 J) of heat as shown below:
Thus, by plugging in, we obtain:

I think that it is D because the higher the molecular mass, the higher it's boiling point. I hope that helped:) Bye!
1 significant figure, because there is no decimal after the zero the zero doesn't count.
Answer:
1.78 × 10⁹ μg
Explanation:
We have to convert 1.78 kg to μg.
Step 1: Convert 1.78 kilograms to grams
We will use the conversion factor 1 kg = 10³ g.
1.78 kg × 10³ g/1 kg = 1.78 × 10³ g
Step 2: Convert 1.78 × 10³ grams to micrograms
We will use the conversion factor 1 g = 10⁶ μg.
1.78 × 10³ g × 10⁶ μg/1 g = 1.78 × 10⁹ μg
