Given:
Density:8.92g/cm3
Volume:25.8 mL
Now we know that
Mass = density X volume
Substituting the given values in the above equation we get:
Mass = 8.92 x 25.8= 230.136 g
= 230136 mg
Answer:
carbon-14
Explanation:
becouse protons and neutrons are nagetivly charged
For a Forty miles above the earth's surface, the temperature at 250k and the pressure at only 0.20 torr, the density of air at this altitude is mathematically given as
d=3.732*10{-4}g/l
<h3>What is the density of air at this altitude?</h3>
Generally, the equation for the ideal gas is mathematically given as
PV=(m/mw)RT
Therefore
d=m/v
d=26,664*20/83.14*250
d=0.37152
d=3.732*10{-4}g/l
In conclusion, the density
d=3.732*10{-4}g/l

Knowing the two variables in this problem are volume (liter) and pressure (atm), we can determine that the law ought to be used would be Boyle's Law.
Boyle's Law: P₁v₁=P₂V₂
Using the question, we can find:
P₁ (initial pressure)=0.24 atm
V₁ (initial volume)=77.0L
P₂ (standard pressure)= 1.00atm
V₂=?
We can rearrange the equation to solve for V₂: V₂=P₁V₁/P₂
Next, we can plug in the values: V₂=
We would receive an answer of 18.48 L. However, it appears that the significant digits would be 3 as both 77.0 and 0.24 have 3 digits. As such, the answer would be 18.5L of gas at 1.00atm.
Two examples of solid precipitation include snow and ice crystals. Other examples could be sleet, hail, and graupel.
