Density = mass / volume
0.601 = m / 7.25
m = 0.601 x 7.25
m =4.35725 g
hope this helps!
Answer:
Kp of the reaction is 0.0215
Explanation:
Step 1: Data given
Partial pressure at the equilibrium of N2 = 0.22 atm
Partial pressure at the equilibrium of O2 = 0.19 atm
Partial pressure at the equilibrium of NO = 0.030 atm
Temperature = 2200 °C
Step 2: The balanced equation
N2(g) + O2(g) ⇌ 2NO(g)
Step 3: Calculate Kp
Kp = (pNO)² /(pO2)*(pN2)
Kp = (0.030)²/(0.19*0.22)
Kp = 0.0215
Kp of the reaction is 0.0215
The answer is C. <span>either have charged particles or be able to form hydrogen bonds with water.

Given the information we have V1=20ml V2=35.25ml (V=volume)
M1=15.71g M2= second mass unknown
Set as proportion: V1 V2
----- = -----
M1 M2
20ml 35.25ml
Cross multiply --------- = ------------ THEN 20ml (M2)= (35.25ml)x (15.71g)
15.71g M2 20ml (M2)= 553.7775ml/g
Divide both sides by 20ml to solve for M2.
20ml (M2) 553.7775ml/g
--------------- = ------------------- then M2=27.688875g
20ml 20ml
Second question we need to find volume but we know Volume=Mass/density.
We need to find density first because we have mass=125.4g only given.
Since we are working with the same alcohol we can use the first V1 and M1 to find density=M/V.
Density= M1/V1 Density= 15.71g/20ml then density=0.7855 g/ml
( It would be the same density if we used V2 and M2)
Now we find the volume of 125.4g with a density of 0.7855g/ml
V= M/D V=125.4g/0.7855g/ml then V=159.64ml
Note: Do not round off until you have reached the end of problem. It will give you a better approximation. Also, round to the largest place which in this case was two decimal places. Do not forget unit of measure.
This is a short answer but because they have the same amount of protons and electrons but different amount of neutron
