Answer:
100°C
Explanation:
The boiling point of water is 100°C and the difference is when will the water start boiling.
28.02g ------ 1 mol
X g ------------ 4.60 mol
X = (28.02×4.60)/1
X = 128,892 g

have to go through it is a great place for you to make me some of the members of your family and I will be happy to help you with this process and if you have any questions or concerns about the dad lowkey or if you need help with the project or if you need help with anything else or just let me know what you need me to do it
First, we determine the number of moles of barium phosphate. This is done using:
Moles = mass / Mr
Moles = 1 / 602
Moles = 0.002
Now, we see from the formula of the compound that each mole of barium phosphate has 2 moles of phosphorus (P). Therefore, the moles of phosphorus are:
0.002 * 2 = 0.004
The number of particles in one mole of substance is 6.02 x 10²³. The number of phosphorus atoms will be:
0.004 * 6.02 x 10²³
2.41 x 10²¹ atoms of phosphorus are present
