Answer:
The correct answer is 783 kg.
Explanation:
To solve this problem, we first must simply add all three values together. We can perform this operation because all three values have the same units of kilograms.
When we add, we get:
258.3 + 271.23 + 253 = 782.53 kg
However, this answer does not have the correct number of significant digits. When adding and subtracting values, we round our final answer to the least amount of decimal places of the numbers we were adding. In this case, that is 0 decimal places, because 253 doesn’t have a decimal place.
Therefore, we should round 782.53 to the ones place. Since the next number is a 5, we round up.
This gives us 783 kg, which is our final answer.
Hope this helps!
Hey nice jeans there, fermi-cutie B))
Answer:
The answer to your question is 2.32 atm
Explanation:
Data
P = ?
n = 0.214
V = 2.53 L
T = 61°C
R = 0.082 atm L/mol°K
Formula
PV = nTR
solve for P
P = nRT/V
Process
1.- Calculate the temperature in K
°K = °C + 273
°K = 61 + 273
= 334
2.- Substitution
P = (0.214 x 0.082 x 334) / 2.53
3.- Simplification
P = 5.86/2.53
4.- Result
P = 2.32 atm
Sodium mn2 and po4 makes sodium
Distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
<h3>What is thermal equilibrium?</h3>
The expression 'thermal equilibrium' makes references to the phenomenon by which two objects interact with each other to exchange heat energy.
Objects in contact can transfer heat to reach a thermal equilibrium state where the temperature is the same for both objects.
In conclusion, distilled water and sealed container are in equilibrium when these objects do not exchange more heat.
