Answer:

1. 43.44g of HCl

2. 26.67 L of HCl

Explanation:

1) Molarity of a solution = number of moles (n) ÷ Volume (V)

According to the provided information in this question,

V = 350 mL = 350/1000 = 0.350L

Molarity = 3.4 M

Using Molarity = n/V

3.4 = n/0.350

n = 3.4 × 0.350

n = 1.19mol

Using the formula below to calculate the mass of HCl;

mole = mass/molar mass

Molar mass of HCl = 1 + 35.5 = 36.5g/mol

mole = mass/MM

mass = 1.19 mol × 36.5g/mol

mass = 43.44g of HCl

2) At STP, HCl has a pressure of 1atm, a temperature of 273K

V = ?

n = 1.19 mol

R = 0.0821 Latm/molK

Using PV = nRT

V = nRT/P

V = 1.19 × 0.0821 × 273/1

Volume = 26.67L

What is the volume of a salt crystal measuring 2.44 × 10–2 m by 1.4 × 10–3 m by 8.4 × 10–3 m?
Dima020 [189]
All solids have an orderly internal structure with repeating bonding patterns between atoms, ions, or molecules. They are called crystal lattices. They are a 3-dimensional arrangement of atoms inside a crystal. The volume of this crystal is:
<span>
Volume = 2.44 × 10^–2 m x 1.4 × 10^–3 m x 8.4 × 10^–3 m = </span>2.87 x 10^-7 m^3
