Answer:
The 3rd one is correct
Explanation:
Protons and neutrons have approximately the same mass, about 1.67 × 10−24 grams, which scientists define as one atomic mass unit (amu) or one Dalton. Each electron has a negative charge (−1) equal to the positive charge of a proton (+1). Neutrons are uncharged particles found within the nucleus.
Answer: 3.613x10^24
Explanation: Avogadro’s number represents the number of atoms in one mole of substance: 6.022x10^23 atoms/mole. Multiplying the number of moles by this number reveals that, in this sample, 3.613x10^24 atoms of methane are present.
Answer: no you need a balance skall to make it the correct balance that you want. yes the hypothesis is correct because you change the balance with your balance scale so obviously it's going to make your hypothesis higher.
