Answer:
See Explanation
Explanation:
Let the mass of salt be x
Let the mass of solution be 10 g
Percentage by mass of salt = 0,25%
So;
Percent concentration of salt = mass of salt/mass of solution * 100
0.25 = x/10 * 100
0.25 * 10/100 = x
x= 0.025 g of salt
Let the mass of water be y
Since mass of solution = mass of salt + mass of water
10 g = 0.025 g + y
y = 10 g - 0.025 g
y = 9.975 g
<em>Transport of substances across cell membrane:</em>
<em>Carrier proteins facilitate transport of material across a membrane by changing its shape to allow a substance to pass through its membrane. It transports substances from high concentration to lower concentration levels.</em>

First, determine how many moles of NaCl you have
Atomic weight sodium = 22.989769
Atomic weight chlorine = 35.453
Molar mass NaCl = 22.989769 + 35.453 = 58.442769 g/mol
Moles NaCl = 15.4 g / 58.442769 g/mol = 0.263505653 mol
Now molarity is defined as moles/liter, so let's set up an equation for the number of liters we can make.
molarity = moles/liter
Substitute the known values
5.00 = 0.263505653/liter
And solve for liters
5.00 = 0.263505653/liter
5.00* liter = 0.263505653
liter = 0.263505653/5.00
liter = 0.052701131
So you can make 0.0527 liters of the solution. Or 52.7 ml</span>
