marissa [1.9K]

Answer:

1.034 L

Explanation:

P1 V1 = P2 V2

P1 V1 / P2 = V2

2.4 (2.5) / 5.8 = V2 = 1.034 L

A solution is prepared by dissolving 23.7 g of cacl2 in 375 g of water. the density of the resulting solution is 1.05 g/ml. the
alekssr [168]
<span>The density of the solution =1.05 g/ml.
</span><span>The total mass of the resulting solution is = 398.7 g (CaCl2 + water)
</span>
Find moles of CaCl2 and water.
Molar mass of CaCl2 = 110 (approx.)

Moles of CaCl2 = 23.7 / 110  = 0.22
so, moles of Cl- ion = 2 x 0.22 = 0.44  (because each molecule of CaCl2 will give two Cl- ions)
Moles of water = 375 / 18 = 20.83

Now, Mole fraction of CaCl2 =  (moles of CaCl2) / (total moles)

total moles = moles of Cl- ions + moles of Ca2+ ions + moles of water

                  = 0.44 + 0.22 + 20.83

=21.49


So, mole fraction = 0.44 / (21.49) = 0.02

Guess what !!! density is not used. No need

1. What happens when two unbalanced forces act on an
Mekhanik [1.2K]

Answer:

Explanation:

Equilibrium is the state in which the resultant of all forces acting on an object is zero. This implies that the object do not rotate or move, but well balanced at a point. Equilibrium can either be dynamic or static.

When two unbalanced forces act on an object, the object move in the direction of the greater force. This effect nullifies equilibrium of the object.

i. Tim versus Elena and Anne - Unbalanced balanced

⇒  70 - (100 + 30) = -60N

ii. Elena versus Tim and Anne - Balanced

⇒ 100 - (70 + 30) = 0N

iii. Anne versus Tim and Elena - Unbalanced

⇒ 30 - (70 + 100) = -140N
