How many grams are in 50.0 mL 2.0 M of HCl?

Please help me!!! I think the answer is 3.57g but I am not sure.

Thank you :)

mols HCl = M x L = 2.0M x 0.050L = 0.10

g = mols x molar mass = 0.1 x 36.5 = 3.65.
H = 1
Cl = 35.5
HCl = 36.5 g/mol.

To determine the number of grams in 50.0 mL of 2.0 M HCl, we need to use the molarity and the molar mass of HCl.

To start, let's calculate the number of moles of HCl in 50.0 mL of 2.0 M solution:

Molarity (M) = moles of solute / liters of solution

Rearranging the equation, we have:

moles of solute = Molarity (M) * liters of solution

Since we are given 50.0 mL and the molarity is 2.0 M, we convert the volume to liters by dividing by 1000:

50.0 mL = 50.0 mL * (1 L / 1000 mL) = 0.050 L

Now, we can calculate the moles of HCl:

moles of HCl = 2.0 M * 0.050 L = 0.1 moles

Next, we need to find the molar mass of HCl. The molar mass of HCl is the sum of the atomic masses of hydrogen (H) and chlorine (Cl):

Molar mass of HCl = (1.00784 g/mol for hydrogen) + (35.453 g/mol for chlorine) = 36.46 g/mol

Finally, we can calculate the grams of HCl:

grams of HCl = moles of HCl * molar mass of HCl = 0.1 moles * 36.46 g/mol = 3.646 g

So, the correct answer is 3.646 grams of HCl, not 3.57 grams as you initially guessed.

I hope this helps!
