lets work back. The formula to find density is d= m/v. fill in the values you know.
10 = 500/v
well, we don't need to use a calculator. dividing by ten is going to the left once, and removing one value of ten.
this means you have a volume of 50.
Hope this helps! :D
Answer:
Scientific Explanation of weather change and cause storms is described below in detail.
Explanation:
The weather is just the nature of the environment at any time, including items such as warmth, rainfall, air pressure, and cloud shelter. Daily variations in the weather are due to storms and winds. Seasonal variations are due to the Earth spinning nearby the sun. Warm beginnings often produce stormy weather as the heated air mass at the exterior rises above the cool air mass, creating clouds and storms.
Answer:
The right answer is C. The molecules of solid CO2 are much closer together than the molecules of CO2 gas.
Answer:
118.776 mmHg
Explanation:
The equation of the reaction is;
C4H10(g) + 13/2 O2(g) ------> 4CO2(g) + 5H20(g)
Now the mole ratio according to the balanced reaction equation is;
1 : 6.5 : 4 : 5
Hence, the total number of moles present = 1 + 6.5 + 4 + 5 = 16.5 moles
Mole fraction of water vapour = 5/16.5 = 0.303
We also know that;
Partial pressure= mole fraction * total pressure
Partial pressure of H20(g) = 0.303 * 392 mmHg = 118.776 mmHg
Answer:
<h2>0.4 M</h2>
Explanation:
The molarity of the NaOH solution can be found by using the formula
c is the molarity
n is the number of moles
v is the volume in L
From the question we have
We have the final answer as
<h3>0.4 M</h3>
Hope this helps you
