Answer:
3.937 x 10⁻⁸ inches
Explanation:
Data Given:
Atomic radium in pm (picometer) = 1.00 x 10² pm
Atomic radium in inches = ?
1 pm = 10⁻¹² m
Solution:
First convert picometer to meter
As we Know
1 pm = 10⁻¹² m
then
1.00 x 10² pm = X meter
Do cross multiplication
X meter = (1.00 x 10² pm)(10⁻¹² m) / 1 pm
X meter = 1 x 10⁻⁹ m
So, 1.00 x 10² pm equal to 1 x 10⁻⁹ m
Now convert meter to inches
As
1 m = 39.37 inches
1 x 10⁻⁹ m = X inches
Do cross multiplication
X inches = (39.3701 inches)(1 x 10⁻⁹ m ) / 1 m
X inches = 3.937 x 10⁻⁸ inches
So,
1.00 x 10² pm = 3.937 x 10⁻⁸ inches
so the radius is 3.937 x 10⁻⁸ inches
Answer:
more dense;change to a liquid to a solid
Explanation:
At high pressure , the gases volume is reduced ,resulting in an increased density.
The volume of the substance is 61.4 litres.
Explanation:
Specific density is the ratio of density of a substance at a given temperature with the density of reference substance.
Data given:
mass = 750 grams
specific gravity = 12.2
volume=?
The formula to be used:
Specific gravity = 
suppose the other substance is water so its density is 1g/ml at 4 degrees
Putting the values to the equation:
density of the object = 1 x12.2
density of the substance = 12.2
Now using the formula:
density = 
putting the values in the equation:
volume = 
= 61.4ml is the volume of the substance.
