Step-by-step explanation:
The formula for percent error is: (M-A)/A x 100
M= the amount of the sample measured
A= the exact value of the sample
And the value of M-A is always positive
So, 2.75-2.699= .051g/cm3, and .051/2.699=.01889
.01889 x 100=1.889% or 1.9% error
Step-by-step explanation:
Let x be the number
6+4x=42
4x=36
x=9
