Answer:
<h3>The answer is 11 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula

From the question
mass = 3025 g
volume = 275 mL
We have

We have the final answer as
<h3>11 g/mL</h3>

Answer:
0.289J of heat are added
Explanation:
We can relate the change in heat of a substance with its increasing in temperature using the equation:
q = m*ΔT*S
<em>Where Q is change in heat</em>
<em>m is mass of substance (In this case, 0.0948g of water)</em>
<em>ΔT = 0.728°C</em>
<em>S is specific heat (For water, 4.184J/g°C)</em>
Replacing:
q = 0.0948g*0.728°C*4.184J/g°C
q = 0.289J of heat are added
Answer:
The answer is
<h2>13.84 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual volume = 22.4 L
error = 22.4 - 19.3 = 3.1
The percentage error is

We have the final answer as
<h3>13.84 %</h3>
