A plant cell has a solute potential of -2.0 bars and pressure potential of 0.0. Its water potential is -2 bar. The cell will gain water or swell.

<h3>What is Water Potential ?</h3>

Water Potential is the potential energy of water in a system per unit volume relative to pure water , when both pressure and temperature are kept same. Water potential is never positive. It is expressed in kPa (Kilopascals). The symbol of water potential is ψ.

<h3>How to find the Water Potential ?</h3>

To find the water potential use this formula

\Psi = \Psi_{s} + \Psi_{p}

where,

ψ = Water Potential

\Psi_{s} = Solute Potential

\Psi_{p} = Pressure potential

Now put the value in above expression we get

\Psi = \Psi_{s} + \Psi_{p}

   = -2.0 + 0.0

   = - 2 bar

Thus from the above conclusion we can say that A plant cell has a solute potential of -2.0 bars and pressure potential of 0.0. Its water potential is -2 bar. The cell will gain water or swell.

if 1.386 g of mg ribbon combusts to form 2.309 g of oxide product, calculate the experimental mass percent of oxygen from this d
Pavlova-9 [17]

1.386 g of Mg ribbon combusts to form 2.309 g of oxide product. The mass percent of oxygen in the oxide is 40.0 %.

Let's consider the reaction for the combustion of Mg.

Mg + 1/2 O₂ ⇒ MgO

1.386 g of Mg combusts to form 2.309 g of MgO. We want to determine the mass of oxygen in MgO. According to Lavoisier's law of conservation of mass, matter is not created nor destroyed over the course of a chemical reaction. Then, the mass of Mg in the reactants is equal to the mass of Mg in MgO. The mass of the magnesium oxide is the sum of the masses of magnesium and oxygen. The <u>mass of oxygen in the oxide</u> is:

mMgO = mMg + mO\\mO = mMgO - mMg = 2.309 g - 1.386 g = 0.923 g

We can calculate the mass percent of O in MgO using the following expression.

\% O = \frac{mO}{mMgO} \times 100\% = \frac{0.923 g}{2.309g} \times 100\%  = 40.0 \%
