C.) protons , the nucleus contains 2 subatomic particles , one protons & neutrons ( protons have a + charge & neutrons have no electrical charge
<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.

Answer:</h3>
0.3093 g of glucose are consumed each minute by the body.
<h3>
Explanation:</h3>
- During cellular respiration glucose is broken down in presence of oxygen to yield energy, water and carbon dioxide.
- The equation for the reaction taking place during cellular respiration is;
C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂
We are required to calculate the amount of glucose in grams;
<h3>Step 1: Calculate the moles of glucose broken down</h3>
From the equation, the mole ratio of glucose to Oxygen is 1 : 6
Moles of Oxygen in a minute is 1.03 × 10^-2 moles
Therefore, moles of glucose will be;
= (1.03 × 10^-2)÷6
= 1.717 × 10^-3 moles
<h3>Step 2: Mass of glucose </h3>
Mass is given by multiplying the number of moles with molar mass
mass = moles × molar mass
Molar mass glucose is 180.156 g/mol
Therefore;
Mass = 1.717 × 10^-3 × 180.156 g/mol
= 0.3093 g
Hence, 0.3093 g of glucose are consumed each minute by the body.
