Answer:
The pressure inside the bottle is 92.678 atm.
Explanation:
An ideal gas is characterized by three state variables: absolute pressure (P), volume (V), and absolute temperature (T). The relationship between them constitutes the ideal gas law, an equation that relates the three variables if the amount of substance, number of moles n, remains constant and where R is the molar constant of the gases:
p×v=n×r×t
In this case:
P= ?
V= 500 mL= 0.500 L
n= 60 g* = 2.07 moles
R= 0.082
T= 0 C= 273 K
Replacing:
P* 0.500 L= 2.07 moles* 0.082 * 273 K
Solving:
P= 92.678 atm
The pressure inside the bottle is 92.678 atm.
To find how many atoms are in the compound, we first have to find how many moles there are. The numbers in the subscript tell you how many moles of each element are present in the compound. Therefore, to find the number of total moles, we can add up each of the numbers in the subscript:
Cu₂Mg₁H₁O₁ *when there is no number under an element, it is implied that there is 1 mole of the element
2+1+1+1=5 moles
We can then use Avogadro's number and dimensional analysis to find how many atoms are in the compound (Avogadro's number is 6.02x10^23):
5 moles (6.02x10^23/1 mole)= 3.01x10^24 atoms
M=(mols/L) so M=(9.0/2.5) which is 3.6M
Answer:
it is calcium and bromine
Explanation:
this is because they are both ionic compounds
