Answer:
Number of moles = 2.89 mol
Explanation:
Given data:
Number of moles of sugar = ?
Mass of sugar = 990 g
Solution:
Formula:
Number of moles = mass/molar mass
Molar mass of C₁₂H₂₂O₁₁:
12× 12 + 22×1.008 + 16×11 = 342.2 g/mol
Number of moles = 990 g / 342.2 g/mol
Number of moles = 2.89 mol
The answerrrrrr isssss B I think
It would be 100.60 because we're adding like to the atmosphere it connects to lubricator and then it turns so that's 100.60
<u>Answer: </u>The volume occupied by
at STP is 0.56 L.
<u>Explanation:</u>
To calculate the number of moles, we use the equation:

We are given:
Given mass of oxygen = 0.80 g
Molar mass of oxygen = 32 g/mol
Putting values in above equation, we get:

<u>At STP:</u>
1 mole of a gas occupies 22.4 L of volume.
So, 0.025 moles of oxygen gas will occupy =
of volume.
Hence, the volume occupied by
at STP is 0.56 L.
