Answer:
13.9atm
Explanation:
Use Boyle's Law: P1V1 = P2V2
Manipulate the equation: P2 = P1V1/V2
Substitute the values: P2 = (1.31atm)(5.51L)/0.520L
P2 = 13.88096atm
Optionally round to 3 sig figs to get 13.9atm
The correct answer is protons and electrons
Answer:
Newer
Explanation:
older fossils and rocks are found in lower strata than younger fossils and rock layers because the top layer fossils have not been there as long as the bottom layer fossils to be found deeper in the ground
Answer:
a) Molar fraction:
Methane: 67,5%
Ethane: 25,1%
Propane: 7,4%
b) Molecular weight of the mixture: 25,16 g/mol
Explanation:
with a basis of 100 kg:
Moles of methane:
500 g × = 31,2 moles
Mass of ethane
350 g × = 11,6 moles
Mass of propane
150 g × = 3,4 moles
Total moles: 31,2 moles + 11,6 moles + 3,4 moles = <em>46,2 moles</em>
Molar fraction of n-methane:
=67,5%
Molar fraction of ethane:
= 25,1%
Molar fraction of propane:
= 7,4%
b) Average molecular weight:
= <em>25,16g/mol</em>
