![\boxed{\text{6.95 u; Li}}](https://tex.z-dn.net/?f=%5Cboxed%7B%5Ctext%7B6.95%20u%3B%20Li%7D%7D)
Explanation:
1. Atomic mass of T
To get the atomic mass of T, you calculate the weighted average of the atomic masses of the isotopes.
That is, you multiply the atomic mass of each isotope by a number representing its relative importance (e.g.., its percent of the total).

2. Identity of T
Lithium has an atomic mass of 6.64 u.
Element T is lithium.
<span>Answer:
Equation:
N2(g) + 3H2(g) → 2NH3(g)
Check for limiting reactant
Molar mass N2 = 28g/mol
mol N2 in 31,500g = 31,500/28 = 1,125 mol N2
This will require 1,125*3 = 3,375 mol H2
Molar mass H2 = 2g/mol
Mol H2 in 5,220g = 5,220/2 = 2,610 mol H2
The H2 is limiting
From the equation:
3 mol H2 will produce 2mol NH3
2610 mol H2 will produce 2610*2/3 = 1,740 mol NH3
Molar mass NH3 = 17g/mol
Mass of 1740 mol NH3 = 1740*17 = 29,580g NH3 produced
Mass of NH3 produced = 29.6kg</span>

bc it goes from having the potential to move to moving sorry if im wrong tho
Answer:
Conversion gives 42,107 km in total
Explanation:
A marathon covers 26 miles and 285 yards.
If 1 kilometer is 0.6214 miles, then how many kilometers are 26 miles, then:
1 km = 0.6214 miles
X = 26 miles
X = 41,841 km
Now if 1 yard is 36 inches, how many inches is 285 yards?
1 yard = 36 inches
285 yards = X
X = 10260 inches
If an inch is equal to 2.54 cm, how many centimeters are 10260 inches?
1 inch = 2.54 cm
10260 cm = X
X = 26060.4 cm
And 26060.4 cm is 0.260604 km
Finally, the sum of the distance would be:
41.841 km + 0.260604 km = 42.107 km
The difference is in how the vitamins are dissolved into the body. Vitamin C is water soluble, so your kidneys are able to filter them out and expel them from the body. Whereas vitamin A is fat soluble and the body cannot get rid of those vitamins and just store them inside the body.
