densk [106]1 year ago
3 0

Answer:

             1.73 × 10²⁴ Molecules

Explanation:

Relation between number of molecules and moles is,

No. of Molecules = Moles × 6.022 × 10²³ Molecules/mol

No. of Molecules = 2.88 mol × 6.022 × 10²³ Molecules/mol

No. of Molecules = 1.73 × 10²⁴ Molecules

If a 0.4681 g Mg strip reacts with 0.650 M HCl in a 139.3 mL flask at 25oC, what is the minimum volume (mL) of HCl needed to com
Marizza181 [45]
The reaction between the magnesium, Mg, and the hydrochloric acid, HCl is given in the equation below,

    Mg + 2HCl --> H2 + MgCl2

The number of moles of HCl that is needed for the reaction is calculated below.
    n = (0.4681 g Mg)(1 mol Mg/24.305 g Mg)(2 mol HCl/1 mol Mg)
    n = 0.0385 mols HCl

From the given concentration, we calculate for the required volume. 
    V = 0.0385 mols HCl/(0.650 mols/L)
     V = 0.05926 L or 59.26 mL

<em>Answer: 59.26 mL of HCl</em>

A shipping container is 9 meters long, 4 meters tall and 3 meters wide. It has a mass of 3,000 kilograms.what is the density of
Rina8888 [55]

The shipping container have a density of 27.77 kg/m³.

Explanation:

The formula for density is:

density = mass / volume

volume of the container = 9 m × 4 m  × 3 m

volume of the container = 108 m³

density of the container = 3000 kg / 108 m³

density of the container = 27.77 kg/m³
