How many moles of Lithium Fluoride will you need to add to 250.0 mL of water to make a 5.00 M solution?

Alex17521 [72]

Answer:

1.25 mol LiF

Explanation:

5.00 M solution means

5.00 mol LiF in 1 L solution=1000mL

x mol LiF in 250 mL

x = 5.00*250/1000 = 1.25 mol LiF

(f) what is the observed rotation of 100 ml of a solution that contains 0.01 mole of d and 0.005 mole of l? (assume a 1-dm path

never [62]

Answer: .01 moles of D to .005 moles of L ~ so, .01+.005 = .015 total; using this total value, divide the portions of D and L. so .01/.015 to .005/.015 ~ 67% D to 33% L. And thus, the enantiomer excess will be 34%.

Convert 9.32x 10 23ª atoms of au to moles of au

7nadin3 [17]

Answer:

$\huge\boxed{\sf no.\ of\ moles = 1.55\ moles }$

Explanation:

Given:

Number of atoms = $9.32 \times 10^{23}$ atoms

Avogadro's Number = $6.023 \times 10^{23}$ atom / mol

Required:

Moles = ?

Formula:

$\displaystyle No.\ of\ moles = \frac{no. \ of \ atoms }{avogadro's \ no.}$

Solution:

$\displaystyle no. \ of \ moles = \frac{9.32\times 10^{23}}{6.023 \times 10^{23}}$

no. of moles = 1.55 moles

$\rule[225]{225}{2}$

Hope this helped!
