Answer:
c) Both a) and b)
Explanation:
please mark me brainliest
Explanation:
First you must calculate the number of moles in this solution, by rearranging the equation. No. Moles (mol) = Molarity (M) x Volume (L) = 0.5 x 2. = 1 mol.
For NaCl, the molar mass is 58.44 g/mol. Now we can use the rearranged equation. Mass (g) = No. Moles (mol) x Molar Mass (g/mol) = 1 x 58.44. = 58.44 g.
Answer:
positive force → balanced force → negative force
Explanation:
np
The mass of nucleons (and thus of the nucleus) is roughly 1000 times greater than that of electrons.
