7. Calculate the amount of sodium hydroxide you will need to make 250 mL of a 0.1 M solution of sodium hydroxide.
tresset_1 [31]

Answer:

1 g

Explanation:

Given data:

Volume of solution = 250 mL (250 mL × 1 L/1000 mL = 0.25 L)

Molarity of solution = 0.1 M

Amount of sodium hydroxide = ?

Solution:

Molarity = number of moles / volume in L

0.1 M = number of moles /0.25 L

Number of moles = 0.1 M × 0.25 L

            M = mol/ L

Number of moles = 0.025 mol

Mass of sodium hydroxide:

Mass = number of moles × molar mass

Mass = 0.025 mol ×40 g/mol

Mass = 1 g

Fluorine gas and water vapor react to form hydrogen fluoride gas and oxygen. What volume of hydrogen fluoride would be produced
mafiozo [28]

Answer:

Hi, the question is incomplete. However, the question is about the calculation of volume of a product when the volume of one of the reactants is provided.

9.587 cm^3

Explanation:

The balanced equation for the chemical reaction is shown below:

2F_{2(g)} + 2H_{2}O_{(g)} ⇒4HF_{(g)} + O_{2(g)}

In the chemical reaction above, 2 moles of water produced 4 moles of hydrogen fluoride. If 4.8 cm^3 of water were consumed, we can calculated the volume of hydrogen fluoride that would be produced as follow:

Using STP, 1 mole of gas has a volume of 22.4 L

Thus, 4.8 cm^3 = 0.0048 L is equivalent to 2.14*10^-4

since 2 moles of water produced 4 moles of hydrogen fluoride, therefore, 2.14*10^-4 would produced 2*2.14*10^-4 = 4.28*10^-4 moles

we can convert the moles to L by multiplying with 22.4

volume of hydrogen fluoride = 4.28*10^-4 * 22.4 = 0.009587 L = 9.587 cm^3
