Answer:
- Deep red fire is about 600-800° Celsius
- Answer: {1102.91}
Given: K= °C + 273.15
K = 1,376.06
Since you’re trying to find C (Celsius) you want to get C by itself in the problem. So you subtract 273.15 from that side. Anything you do to one side of the equal sign you have to do to the other side, so also subtract 273.15 from K (1,376.06).
1,376.06 - 273.15 = {1102.91°C}
That is True XD
Hope that helps :D

Answer:
The correct answer is 0.92 g
Explanation:
The density is defined as the mass per unit of volume:
Density= mass/volume
From the data provided:
volume= 5.4 L
density= 0.17 g/L
Thus, to calculate the mass of helium:
mass= density x volume = 0.17 g/L x 5.4 L= 0.918 g ≅ 0.92 g
