Answer:
a. 0.528 M ..
Explanation:
Hello!
In this case, since the given by-mass percent can be written as:
By using the density and molar mass of the solute, cadmium sulfate, we can compute the molarity, by also making sure we convert from mL to L of solution:
Thereby, the answer is a. 0.528 M .
Best regards.

Grey basically is formed by combining black and white colors together.
In this case, one would have to explore other options.
<h3>What kind of colors will form grey?</h3>
The following color combinations can form grey:
- Orange and Blue
- Red and Green
- Yellow and Purple.
By adjusting the other colors, variations of hue will be observed. It is to be noted that the Gizmo is unaccessible on this platform hence the general answer.

Answer:
The answer to your question is 24.32 g
Explanation:
Data
Atomic weight = ?
HCl volume = 125 ml
Molarity = 0.2
mass of metal = 0.304 g
Balanced chemical equation
M + 2HCl ⇒ MCl₂ + H₂
Process
1.- Calculate the moles of HCl
Molarity = moles / volume (L)
- Solve for moles
moles = Molarity x volume
moles = 0.2 x 0.125
= 0.025
2.- Calculate the moles of the Metal
1 mol of M ----------------- 2 moles of HCl
x ----------------- 0.025 moles of HCl
x = (0.025 x 1) / 2
x = 0.0125 moles of HCl
3.- Calculate the atomic weight of the metal
atomic weight ---------------- 1 mol
0.304 g ---------------0.0125 moles
Atomic weight = (1 x 0.304) / 0.0125
Atomic weight = 24.32 g
