we can see here in the option B give us H+ which is arrhenius acid
I would say E because you shouldn't/can't do any of those! Dangerous!!!
The number of mole present in 87.653 g of lead(II) oxide is 0.393 mole
<h3>Description of mole </h3>
The mole of a substance is related to it's mass and molar mass according to the following equation:
Mole = mass / molar mass
With the above formula, we can determine the mole of lead(II) oxide. Details below:
<h3>How to determine the mole present in 87.653 g of lead(II) oxide</h3>
- Mass of lead(II) oxide = 87.653 g
- Molar mass of lead(II) oxide = 223.2 g/mol
- Mole of lead(II) oxide =?
Mole = mass / molar mass
Mole of lead(II) oxide = 87.653 / 223.2
Mole of lead(II) oxide = 0.393 mole
Thus, 87.653 g of lead(II) oxide contains 0.393 mole
