The answer is C, they are found in the outermost layer of the atom. hope this helps, have an amazing day :)
The mass is simply the product of volume and density. But
first, let us convert the volume into cm^3 (cm^3 = mL):
volume = 2.5 cups * (240 mL/cup)
volume = 600 mL = 600cm^3
So the mass is:
mass = 600 cm^3 * (1 g / cm^3)
<span>mass = 600g</span>
I believe it's C. 30
you have to find the pattern, so 15/3= 5
6x5= 30

Explanation:
water traps heat and holds it deep inside the ocean .....
I think it's correct answer
The number of grams of NaOH that are needed to make 500 ml of 2.5 M NaOH solution
calculate the number of moles =molarity x volume/1000
= 2.5 x 500/1000 = 1.25 moles
mass = moles x molar mass of NaOH
= 1.25 x40= 50 grams of NaOH
