Answer:
B) hyperbaric oxygen chamber to increase PO2 and clear CO from the body
Explanation:
Carbon monoxide poisoning occurs from the breathing in of poisonous gas, carbon monoxide (CO) at high levels. Large exposures of the gas can result in the loss of consciousness, seizures, or even death.
<u>Hyperbaric oxygen is used in treatment of carbon monoxide poisoning, as it hasten the dissociation of CO from carboxyhemoglobin and also cytochrome oxidase to a greater extent as compared to normal oxygen. It also enhance the oxygen transport to tissues by the plasma.</u>
Answer: 0.118M
Explanation:
The formula for molarity is: 
First, we need to find the number of moles of NaCl.
Next, we must convert millimeters to liters. We can do that by dividing the number of mL by 1000.
Now we have our needed data! All we need to do now is plug in our data to the molarity formula.
I hope this helps! Pls mark brainliest!! :)
Answer: N = 2.78 × 10^23 atoms
There are N = 2.78 × 10^23 atoms in 70g of Au2cl6
Completed Question:
Calculate the number of gold atoms in a 70g sample of gold(III) chloride . Be sure your answer has a unit symbol if necessary, and round it to significant digits
Explanation:
Given:
Molar mass of Au2cl6 = 303.33g/mol
Mass of Au2cl6 = 70g
Number of moles of Au2cl6 = 70g/303.33g/mol = 0.231mol
According to the chemical formula of Au2cl6,
1 mole of Au2cl6 contains 2 moles of Au
Number of moles of Au = 2 × 0.231mol = 0.462mole
There are 6.022 × 10^23 atoms in 1 mole of an element.
Number of Atom of gold in 0.462 mole of gold is:
N = 0.462 mol × 6.022 × 10^23 atoms/mol
N = 2.78 × 10^23 atoms
