Answer:

1.23 g

Explanation:

<em>A chemist adds 1.55 L of a 0.00582 M calcium sulfate solution to a reaction flask. Calculate the mass in grams of calcium sulfate the chemist has added to the flask.</em>

Step 1: Given data

  • Volume of the solution (V): 1.55 L
  • Molar concentration of the solution (C): 0.00582 M (0.00582 mol/L)

Step 2: Calculate the moles (n) of calcium sulfate added

We will use the following expression.

n = C × V

n = 0.00582 mol/L × 1.55 L

n = 0.00902 mol

Step 3: Calculate the mass corresponding to 0.00902 moles of calcium sulfate

The molar mass of calcium sulfate is 136.14 g/mol.

0.00902 mol × 136.14 g/mol = 1.23 g

You wish to prepare 100 mL of 0.600 M HCl from concentrated HCl (12.85 M). You are provided with a 100 mL volumetric flask and a
Soloha48 [4]

Answer:

Because we need to dispense 4.7 mL, the volume reading in the pipet is the 5.3 mL line.

Explanation:

First we use C₁V₁=C₂V₂ in order to <u>calculate the required volume of concentrated HCl</u> (V₁):

12.85 M * V₁ = 0.600 M * 100 mL

V₁ = 4.7 mL

<u>So we need to dispense 4.7 mL of the concentrated HCl solution</u>. The mark in the pipet that would contain that volume would be 10.0 - 4.7 = 5.3 mL
