I am pretty shore the answer is d and plaz mark as brainliest
Answer:
It's 0.07
Explanation:
1.65/23
Cause three me formula is mass upon the molecular mass so when you divide them you would get 0.07
Answer:
MgCl2 = 24 + 2(35.5)
= 95
mass of substance = mol × molar mass
= 0.119 × 95
= 11.305 g
IDK THE ANSWER BUT I THINK I NEED HELP ON THIS ONE TO
Mass =70 ( Mass of protons=1 ,Mass of neutrons =1, Mass of electron =0.0005(can be ignored))
Therefore, 40 +30=70
Charge= -2 ( it is taking in/attracting electrons to its shell) base on the proton number you are able to identify if it is attracting or releasing an electron, if the electron number is more than proton number then it is attracting therefore resulting in a negative charge vice versa for releasing an electron.
