Answer:
if you mean 2 hours and 25 minutes than 8:45
Explanation:
Sodium hypochlorite chemical name would be NaOCl. Then, the molecular weight should be:23 + 16 + 35.5 = <span>74.5 g/mole
Molarity unit is mole of molecule divided by 1000ml of solvent, in this case water. Then for 32.4g of molecule with 499ml solvent it would be:
32.4g / (74.5g/mole) / (1000ml/499ml)= 0.87 m</span>
Answer:
Electricity is made at a generating station by huge generators. The current is sent through transformers to increase the voltage to push the power long distances. The electrical charge goes through high-voltage transmission lines that stretch across the country.
Answer:
The mass of ammonia (NH3) that contains hydrogen atoms is g.
Explanation:
As atoms of hydrogen = 1 mole of the hydrogen atom
Therefore, atoms of hydrogen moles of the hydrogen atom.
Now, there are 3 moles of hydrogen atoms in 1 mole of ammonia .
As the mass of 1 mole of ammonia is 17g, so
when there are 3 moles of hydrogen atoms, then the mass of ammonia = 17 g
Therefore, when there are moles of hydrogen atoms, then the mass of ammonia g.
Hence, the mass of ammonia that contains hydrogen atoms is g.
