The relative mass of each element can be found from the periodic table (the larger number). For instance, P2O5, P = 31.0 O = 16.0, thus the formula mass (Mr) is 2(31) + 5(16) = 142 amu (atomic mass unit). I used a not really specific periodic table. Maybe your teacher is referring to open Schoology (a website where teacher can post files or announcements to students in his or her class). Sorry if i got something mistaken.
Think it is b
but i am not sure at all
Answer:
I'm pretty sure the ionic structure is C, sorry this is only one answer tho : , (
Explanation:
The partial pressure of carbon dioxide is 75 torr.
<h3>What is Dalton's theory?</h3>
Dalton's theory of gas states that total pressure of the mixture of gas sample is equal to the sum of the partial pressure of all the gases present in that sample.
Given that,
- Total pressure of mixture = 825 torr
- Partial pressure of Nitrogen = 600 torr
- Partial pressure of oxygen = 150 torr
- Partial pressure of carbon dioxide = ?
On putting values, we get
Partial pressure of carbon dioxide = 825 - (600 + 150) = 75 torr
Hence Partial pressure of carbon dioxide is 75 torr.
