Answer:

1. molarity is = 0.1174

2. molarity is = 9.3

3. molarity is =0.009392

Explanation:

Q#1.

mass of sucrose is 14.07g

molar mass of sucrose is 342 3g/mol

so, 14.07x1/342.3 = 0.0411

now the volume is of water is 0.35

so, 0.0411/0.35 = 0.1174

Q#2.

concentration is 4.5

so, 4.5x1/1000= 0.0045

then, 0.0411/0.0045 = 9.13

Q#3.

M1M1=M2M2

molarity of the same sucrose is 0.1174

so, diluted in 40mL

and the volumetric flask is 500mL

so, 0.1174x40/500= 0.009392

Magnesium (24.48g) reacts with hydrochloric acid (xg) to produce hydrogen gas (2.04g) and magnesium chloride (96.90g). How much
andriy [413]

Answer:

Mass = 73.73 g

Explanation:

Given data:

Mass of Mg used = 24.48 g

Mass of HCl used = ?

Mass of hydrogen gas produced = 2.04 g

Mass of Magnesium chloride produced = 96.90 g

Solution:

Chemical equation:

Mg + 2HCl   →    MgCl₂ + H₂

Number of moles of Mg:

Number of moles = mass/ molar mass

Number of moles = 24.48 g/ 24.305 g/mol

Number of moles = 1.01 mol

Now we will compare the moles of Mg with HCl from balance chemical equation.

                              Mg             :            HCl

                               1                ;               2

                            1.01              :           2/1× 1.01 = 2.02 mol

Mass of HCl react:

Mass = number  of moles × molar mass

Mass =  2.02 ×  36.5 g/mol

Mass = 73.73 g
