Explanation:
6 (weights) x 3 (distance) = moment
Answer:
3.38 moles.
Explanation:
The following data were obtained from the question:
Mass of copper (Cu) = 215 g
Number of mole of copper (Cu) =...?
The number of mole of copper (Cu) in 215 g can be obtained as follow:
Mass of copper (Cu) = 215 g
Molar mass of copper (Cu) = 63.55 g/mol
Number of mole of copper (Cu) =...?
Mole = mass /Molar mass
Mole of Cu = 215/63.55
Mole of Cu = 3.38 moles
Therefore, 3.38 moles of copper (Cu) is present in the sample.
Answer:
<h2>0.92 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question we have
mass = 16.1 g
volume = 17.5 mL
We have the final answer as
<h3>0.92 g/mL</h3>
Hope this helps you
