Answer:
42
Explanation:
Relative mass = number of protons + number of neutrons
Relative mass = 20 + 22
Relative mass = 42
Answer:
2 moles
Explanation:
Given data:
Moles of water produced =?
Moles of propane = 0.5 mol
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of propane and C₃H₈.
C₃H₈ : H₂O
1 : 4
0.5 : 4/1×0.5 = 2 mol
Thus 2 mole of water are produced from 0.5 moles of propane.
<u>Answer:</u> The mole ratio of H : O in ammonium nitrate is 4 : 3.
<u>Explanation:</u>
We are given a compound named ammonium nitrate having formula
There are 3 elements in this compound which are nitrogen, hydrogen and oxygen.
To calculate the mole ratio, we write the ratio of their subscripts. For this compound, it is:
The mole ratio of H and O for this compound is 4 : 3.
