Answer:
divide by molar mass (12.01 g)
Explanation:
To find the number of moles of the carbon, divide by molar mass (12.01 g).
The number of moles of a substance is given as;
Number of moles =
To solve this problem;
since mass of carbon = 45g
Number of moles = = 3.75moles
Answer:
Explanation:
Hello there!
In this case, according to the given information, it will be possible for us to use the Dalton's law, in order to solve this problem. However, we first need to calculate the mole fraction of oxygen by firstly calculating the moles of each gas:
Next, we calculate such mole fraction as follows:
Then, given the following equation:
So we solve for the total pressure as follows:
