B. The Sun, Earth and the Moon are arranged in a straight line.

Spring (strong) tides occur when the moon is either a full or new moon. During these, the bodies are arranged in a straight line.
Neap (weak) tides occur when the moon is in any quarter phase. During these phases, the earth, moon and sun form a right angle.

If an experiment calls for 0.200mole acetic acid (Hc2H3O2)how many grams of glacial acetic acid do we need?

bija089 [108]

<h3>Molar mass:-</h3>

$\\ \sf\longmapsto HC_2H_3O_2$

$\\ \sf\longmapsto 1u+2(12u)+3(1u)+2(16u)$

$\\ \sf\longmapsto 1u+24u+3u+48u$

$\\ \sf\longmapsto 28u+48u$

$\\ \sf\longmapsto 76u$

$\\ \sf\longmapsto 76g/mol$

No of moles=0.2mol
Given mass=?

$\\ \sf\longmapsto No\:of\;moles=\dfrac{Given\:Mass}{Molar\:Mass}$

$\\ \sf\longmapsto 0.2=\dfrac{Given\:mass}{76}$

$\\ \sf\longmapsto Given\:Mass=0.2\times 76$

$\\ \sf\longmapsto Given\:Mass=1.52g$

a solution was made by mixing sodium chloride () and water (). given that the mole fraction of water is 0.980 in the solution ob

Mnenie [13.5K]

The mass of sodium chloride used was 1.17 grams.

The mole fraction can be calculated by way of dividing the number of moles of 1 factor of an answer via the full variety of moles of all the additives of an answer. it is mentioned that the sum of the mole fraction of all the components inside the solution has to be the same as one.

mass of NaCl given = 64.9 g

mole = mass/molar mass

= 64.9 / 58.5

= 1.109

a mole fraction of water = 0.980

mole fraction of NaCl = 1 - 0.980

= 0.02

1 mole of NaCl = 58.5

mass of NaCl = 58.5 × 0.02

= 1.17 gram

Mole Fraction describes the range of molecules contained within one aspect divided through the whole range of molecules in a given combination. it's miles quite beneficial whilst two reactive-natured components are mixed collectively.
