Answer:
The graph is attached below.
Step-by-step explanation:
Given the line equation
Comparing the line equation with the slope-intercept form
where m is the slope, and b is the y-intercept
Here:
m = -3
b = -2
When
x = 0, then y = -2 ∵ y = -3x - 2 = -3(0) - 2 = -2
When
x = 1, then y = -5 ∵ y = -3x - 2 = -3(1) - 2 = -3 - 2 = -5
The graph is attached below.
4 x 300 = 1200
0.58 x 90 = 52.2
1200 + 52.2 = 1252.2
The mass of hydrogen atoms that measures 54 u is 89.64 x 10^-24
Analysis:
If 1 u = 1.66 x 10^-24, then 54 u = 54 x 1.66 x 10^-24 = 89.64 x 10^-24
