What mass in grams of fructose is contained in 325 ml of a 1.5 m fructose solution

answer

2.7956 * 10^19 photons

givens

formula

e = h * c / λ

w = e / t

solution

e = 6.26 * 10^-34 j*s * 3 * 10^8 m/s /525 * 10^-9 (m)

the meters cancel out. so do the seconds. you are left with joules as you should be.

e =   3.577 * 10^-18 joules

what you have found is the energy of 1 photon.

now you have to find the joules from the watts.

w = e/t

100 * 1 second = 100 joules

1 photon contains 3.577 * 10 ^ - 18 joules

x photon = 100 joules                        

1/x = 3.577 * 10^-18 / 100                           cross multiply

100 = 3.577 * 10 ^ - 18 * x                         divide both sides by 3.577 * 10 ^ - 18

100/3.577 * 10 ^ - 18 = 3.577 * 10 ^ - 18x / 3.577 * 10 ^ - 18

2.7956 * 10^19 photons = x

the acids react with base and the reaction is known as neutralization

one mole of hydronium ion reacts with one mole of hydroxide ion

here

a) hi is a monoprotic acid : one mole of hi will give one mole of hydronium ion

b) csoh is a monohydroxide base : one mole of csoh will give one mole of hydroxide ion

so one mole of hi will react with one mole of csoh

the moles of csoh taken will be calculated from molarity and volume as

thus moles of csoh are

moles of hi required is 0.005425 mol

volume of hi required will be

volume of hi required is 9.86 ml

option a - atoms gain, lose, or share electrons to achieve a full valence shell.

explanation

the octet rule is best explained as atoms gain, lose, or share electrons to achieve a full valence shell complete or to attain electronic configuration of noble gases. the main objective to do this is to attain stability.   the octet rule is a rule that shows the view that atoms of elements serve to join like that each atom has eight electrons in its valence shell, providing it the same electron configuration as a noble gas.
