Is there multiple choice answers
The question is incomplete, the complete question is;
Atom Number of protons Number of electrons Number of neutrons
1 39 39 52
2 40 40 50
3 39 39 54
4 40 40 51
Based on the information that is given, which atom in the table has the highest mass?
a. 1
b. 2
c. 3
d. 4
Answer:
c
Explanation:
The relative atomic mass is given as; number of protons + number of neutrons. If we take the relative atomic mass of each of the options;
1) 39 +52 = 91
2) 40+50 = 90
3) 39 + 54 = 93
4) 40 + 51 = 91
Thus 3 has the highest mass as seen above, hence the answer given.
Answer:
The volume of the flask is<u> 20.245 litres .</u>
Explanation:
We are given with following information-
-------- 1
where R =
Molar mass of 
The given chemical equation is -
--------- 2
Now , calculation -
Mass of 
formed = 118g
Molar mass of = 
Mole = 
Therefore , moles of formed = 
From equation 2 , we get to know that ,
2mole formed from 5 mole 
Therefore , mole formed from 
mole
Moles of used =
R=
Pressure (P)= 1.85atm
Temperature (T)= 322K
Moles of (n)= moles
Applying the formula above in 1 equation , that is
PV = nRT
putting the given values -
V = 20.245 litres.
Hence , the volume of the flask is <u>20.245 litres . </u>
Answer:
Explanation:
· 44 g NaCl Explanation: The problem provides you with the molarity and volume of the target
The answer is rounded to two sig figs, the number of sig figs you have for the molarity of the solution.
