What volume of water should be used to dissolve 19.6 g of LiF to create a 0.320 M solution?
USPshnik [31]

Answer:

2.4 litters of water are required.

Explanation:

Given data:

Mass of LiF = 19.6 g

Molarity of solution = 0.320 M

Volume of water used = ?

Solution:

Number of moles = mass/molar mass

Number of moles = 19.6 g/ 26 g/mol

Number of moles = 0.75 mol

Volume required:

Molarity = number of moles/ volume in L

Now we will put the values in above given formula.

0.320 M = 0.75 mol /  volume in L

Volume in L = 0.75 mol  /0.320 M

     M = mol/L

Volume in L = 2.4 L

To investigate the relationship between enzyme activity and substrate concentration, a student is supposed to prepare a reaction
nikdorinn [45]
As i know for finding the speed of an enzyme to do it's work this formula is used
v=v max *[s]/k m +[s]
km shows the amount of substrate we need to make the enzyme work with half of it's max speed and [s] shows the <span>substrate.
we can say that 0.025/0.25=0.1 so the speed is about 0.1 of we wanted to </span>
investigate at the beginning  (we don't consider [s] in the <span>Denominator to solve it easier)

I REALLY NEED HELP PLEASE!!!!!!!!
Fudgin [204]

Answer: 1. The ratio of the reactant aluminum to the product aluminum sulphate is 2:1

2. Option D. 1,3,2,2

Explanation: 1. From the balanced equation:

2Al + 3H2SO4 -> Al2(SO4)3 + 3H2

2moles of Al produced 1mole of Al2(SO4)3. Therefore, the ratio will be 2:1

2. C2H4 + 3O2 ---> 2CO2 + 2H2O from the equation, the coefficients are 1,3,2,2
