Answer:
Mass of carbon tetrachloride 135.15 g.
Explanation:
Given data:
Volume of carbon tetrachloride = 85.0 mL or 85.0 cm³
Density of carbon tetrachloride = 1.59 g/cm³
Mass of carbon tetrachloride = ?
Solution:
Formula:
D=m/v
D= density
m=mass
V=volume
Now we will put the values in formula:
1.59 g/cm³ = m / 85.0 cm³
m = 1.59 g/cm³ ×85.0 cm³
m = 135.15 g
Answer:
I believe the answer is II and III
Explanation:
I'm not sure if III is right cause I cannot read the last word but I think it's OK.
Hope this helped :)
Answer:
First option
Explanation:
Students 1 and 2 have precise measures yet is is not accurate since they measure around 5.
Explanation:
Given parameters:
Dimension = 8.5in²
we are to convert from in² to cm²
in² = in x in
cm² = cm x cm
1 in = 2.54cm
Using dimensional analysis;
8.5in² x 
= 54.84cm²
We solved this problem using dimensional analysis where we multiplied the unit with 1.
