Answer:
The answer to your question is: 40.8 g of NaN₃
Step-by-step explanation:
NaN₃ mass = ?
nitrogen = 1.2 moles
Equation
2NaN₃ ⇒ 2Na + 3N2
2 moles of NaN₃ ----------------- 3 moles of N₂
x ------------------ 1.2 moles of N₂
x = (1.2 x 2) / 3
x = 2.4/ 3
x = 0.8 moles of NaN₃
MW NaN₃ = 23 + 28
= 51 g
51 g of NaN₃ ----------------- 1 mol
x ----------------- 0.8 mol
x = (0.8 x 51) / 1
x = 40.8 g of NaN₃
Answer:
4
Step-by-step explanation:
In a equilateral triangle, all angles are 60 degree, so 10x+20=60
10x=40
x=4

Answer:
154.34%
Step-by-step explanation:
We are asked to determine what percentage of 357 is 551.
Let us assume that x% of 357 is 551.
So, 
⇒ 
⇒ 
......... (1)
⇒ x = 154.34%
So, it is clear from the step (1) that when we take the basic ratio then multiply with 100, then we will get the percentage. (Answer)
