Density = mass / volume
We know the density and the mass of magnesium.
First, convert 1.35 kg into g:
1 kg = 1000 g
1.35 kg = 1350 g
Now, substitute the values for density and mass into the equation.
1.74 = 1350 / volume ---> Multiply both sides by 'volume':
1.74 x volume = 1350 ---> Divide both sides by 1.74 to find the volume:
volume = 775.86 g/cm^3 (2.d.p.)
Polar bond is formed by 2 non-metal atoms which have a significant difference in electronegativity.
Answer:
I think the correct answer is C.
Explanation:
From the question it can be infered that initially only parent atoms were present in the rock and no daughter atom. So, initially there was only uranium atom and no lead atom. So, in total there were 500+1500= 2000 uranium atom. And no lead tom was there.
Because contains more matter.
