The answer for the following problem is mentioned below.
- <em><u>Therefore the mass of an object is 14.16 grams.</u></em>
Explanation:
Force:
The push or pull on an object with mass that cause change in the velocity
It is a vector quantity.
The formula to calculate the force is:
F = m × a
Given:
Force (F) = -136 N
acceleration (a) = -9.6 m/s^2
To calculate:
mass of the object (m)
We know that,
<em>F = m × a</em>
where,
F represents the force of the object
m represents mass of an object
a is acceleration of an object
From the equation;
-136 = m × -9.6
m =
m = 14.16 grams
<em><u>Therefore the mass of an object is 14.16 grams.</u></em>
Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point. When a solid reaches the temperature of its melting point, it can become a liquid.
Formula: q=m*c*(change in T)
q= 418.6
m=26.86
c= X(unknown)
(Change in T)= (67.3-27.4 = 39.9)
Now you solve for X, I got .391.
So the specific heat of this certain metal is .391 j/gram C
First you need to find the moles of the diluted solution (moles of solute is the *same* in both concentrated and dilute solutions, so once you find moles of diluted solution you can then use this number to find the volume of the stock, or concentrated, solution). The equation for finding Molarity (M)
