Answer:
<h2>Density = 1.67 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 50 g
volume = 30 mL
Substitute the values into the above formula and solve for the density
That's
Wr have the final answer as
<h3>Density = 1.67 g/mL</h3>
Hope this helps you
The answer is the letter C
Answer:
0.8078 Kg
Explanation:
Pressure of water = 0.15 MPa = 1.5 bar
At critical point of water ,temperature = 647 K=374°C
From the ideal gas equation
P×V= m×R×T
Let us assume volume = 1 m^3
1.5 x 105 x 1 = m x 287 x 647
m= 0.8078 kg
the fraction of mass of liquid at 25°C.
Answer:
T2 = 51.6°C
Explanation:
Given:
P1 = 1.01 atm
T1 = 25°C + 273 = 298K
P2 = 1.10 atm
T2 = ?
P1/T1 = P2/T2
Solving for T2,
T2 = (P2/P1)T1
= (1.10 atm/1.01 atm)(298K)
= 324.6 K
= 51.6°C
where Tc = Tk - 273
