Answer:
1.42 moles
Explanation:
25.58 g of H₂O .
Molecular weight of water = 2 x 1 + 16 = 18
1 mole of water = 18 g of water
18 g of water = 1 mole
25.58 g of water = 25.58 / 18 mole
= 1.42 moles .
Answer:
Mixing bleach and ammonia will create a toxic chloramine gas. Exposure to chloramine gas can cause irritation to your eyes, nose, throat, and lungs .
if you do accidentally mix bleach and ammonia, get out of the contaminated area and into fresh air immediately.
hope this help u ☆
All of them are reactants
Given :
Mass of O₂, m = 25.43 g.
To Find :
How many liters of gas will you have at STP.
Solution :
Molecular mass of O₂, M.M = 2 × 16 gram/mole
M.M = 32 gram/mole
Number of moles is given by :
n = m/M.M
n = 25.43/32 mole
n = 0.79 mole
Hence, this is the required solution.
