Answer:

SO has about 0.52 moles, while NO has about 0.83 moles

Explanation:

To calculate the number of moles of a certain molecule, you first need to figure out that molecule's molar mass. For SO, the molar mass is the mass of sulfur combined with the mass of oxygen. 16 + 32=48. For NO, you do a similar thing but with nitrogen. 16+14=30. From here, you can simply divide. 25 grams divided by SO's molar mass of 48 yields about 0.52 moles, while for NO there is about 0.83 moles. Hope this helps!

kirza4 [7]

0.05 * V1 = 250 * 10

 V1 = 2500 / 0.05 

 V1 = 2500 * 20 

 V1 = 50000 mL 

V1 = 50 Liters .

The atomic number of lead is 82. Its mass number is 207?.how many protons neutrons and electros does the atom of lead contain

kupik [55]

Lead have:

82 electrons

82 protons

125 neutrons

Explanation:

The number of electrons and protons are given by the atomic number of the element.

Lead have 82 electrons and 82 protons.

The number of neutrons are given by the difference between the mass number and atomic number.

For lead number of neutrons = 207 - 82 = 125.
