Mole is equal to mass of the element divided by molar mass of the element. that is
mole=mass/molar mass
From periodic table calcium has a molar mass of 40 g/mol
moles is therefore =800g/40g/mol=20moles
I would say that only the only density label is cm^3/g
Answer:
<h2>9000 N</h2>
Explanation:
The force acting on an object given it's mass and acceleration can be found by using the formula
force = mass × acceleration
From the question we have
force = 900 × 10
We have the final answer as
<h3>9000 N</h3>
Hope this helps you
