S, sulfur does not have a noble gas electron.
Answer:
A.0.20M
Explanation:
c 1 V 1 = c 2 V 2
Initial Volume, V1 = 200 mL
Final Volume, V2 = 200 + 400 = 600 mL
Initial Concentration, c1 = 0.60 M
Final Concentration, c2= ?
Solving for c2;
c2 = c1v1 / v2
c2 = 0.60 * 200 / 600
c2 = 0.20M

Answer:
The answer to your question is: 0.373 g
Explanation:
Data
mass = ? g
atoms = 3 x 10 ²¹
AM = 74.92 g
Process
1 mol of As ------------------ 6.023 x 10²³ atoms
x ------------------ 3 x 10 ²¹ atoms
x = 4.98 x 10⁻³ moles
1 mol ------------------------ 74.92 g
4.98 x 10⁻³ moles------- x
x = (4.98 x 10⁻³ x 74.92)/1
x = 0.373 g of As
