The density of the metal object=6.0
Given:
Volume of the metal object=1.5ml
Mass of the metal object=9.0g
To find:
Density of the metal object
<u>Step by Step Explanation:
</u>
Solution:
According to the formula, Density of the metal object can be calculated as
Where, m=mass of the metal object
=density of the metal object
v=volume of the metal object
We know the values of v=1.5ml and m=9.0g
Substitute these values in the above equation we get
=9.0/1.5
=6.0
Result:
Thus the density of the metal object is 6.0
Explanation:
Antoine equation is as follows.
It water is at 
, then values of constants A, B, and C will be as follows.
A = 8.07131, B = 1730.63, C = 233.426
When pressure, P = 2.5 atm then putting these given values into the above equation as follows.
5.40365 = 
T = 
Converting the temperature into Fahrenheit as follows.
= 
= 
Thus, we can conclude that the boiling temperature of the water is .
True, any changes radiations are bsorbed or emitted when an electron moves
B. Lithium has a more protons, neutrons, and electrons.
Answer:
Explanation:
The given number is 6.02 × 10⁹. It is written is scientific notation.
As you see it has two parts:
- The first part are the digits with the decimal point after the first digit. This part is called mantissa. The mantissa can only have one digit, between 1 and 9, before the decimal point.
- The second part is a power of 10. The exponent can be either positive or negative.
If the exponent is negative means that the decimal point must be moved to the left and if the exponent is positive means that the decimal point must be moved to the right.
In the number 6.02 × 10⁹ the exponent is 9, so you must move the decimal point 9 places to the right:
- 6.02 × 10⁹ = 6.02 × 1,000,000,000 - 6,020,000,000,
