What will increase the turgor pressure in a plant

1 answer:

7 0

Answer:

Cell expansion and an increase in turgor pressure is due to inward diffusion of water into the cell, and turgor pressure increases due to the increasing volume of vacuolar sap. A growing root cell's turgor pressure can be up to 0.6 MPa, which is over three times that of a car tire.

Atoms from different substances can never combine with atoms from other substances. Disagree or agree reason why ?

Disagree, because they can come together to form a compound element. Hope it helped!

What is the molality of a solution that has 30mg of K3PO4 dissolved in 40mL of water? (The density of water is 1.00 g/mL)

sweet [91]

Answer:

m = 0.0035 m.

Explanation:

Hello there!

In this case, since the formula for the computation of the molality is:

$m=\frac{n_{solute}}{m_{solvent}}$

We can first compute the moles of solute, K3PO4 by using its molar mass:

$n=30mgK_3PO_4*\frac{1gK_3PO_4}{1000gK_3PO_4}*\frac{1molK_3PO_4}{212.27gK_3PO_4} =1.41x10^{-4}mol$

Next, since the volume of water is 40.0 mL and its density is 1.00 g/mL we infer we have the same grams (40.0 g). Thus, we obtain the following molality by making sure we use the mass of water in kilograms (0.04000kg):

$m=\frac{1.41x10^{-4}mol}{0.0400kg}\\\\m=0.0035m$
