Answer:
10.0 ml and 35.0ml respectively
Explanation:
if A=10.0ml let B be x
Now,
Lets assume the pan is balanced
then,
x = 10.0 ml
Therefore B= 10.0 ml
[Repeat the same process in next question]
Molar mass Na = 23 g/mol
23 g ------------- 6.02 x 10²³ atoms
4.56 x 10⁻² g ----- ? atoms
atoms = 4.56 x 10⁻² x ( 6.02 x 10²³ ) / 23
atoms = 2.74 x 10²² / 23
= 1.19 x 10²¹ atoms
hope this helps!
