The number of milliliters of the solution that you need to give to the patient is calculated as follows
32mg is in 1 ml of the solution
what about 320mg
=( 320mg x 1 ml) /32mg= 10ml
Diffraction:
Diffraction<span> describes how waves bend, or change direction, as they travel around the edges of obstacles. </span>Diffraction<span> occurs in water waves, </span>sound <span>waves, and light waves, but the amount of </span>diffraction <span>depends on the size of the obstacle or opening in relation to the wavelength of the wave.</span>
All the elements in one group have the same number of valence electrons.
Answer: 0.4M
Explanation:
Given that,
Amount of moles of NaOH (n) = ?
Mass of NaOH in grams = 40.0g
For molar mass of NaOH, use the atomic masses: Na = 23g; O = 16g; H = 1g
NaOH = (23g + 16g + 1g)
= 40g/mol
Since, n = mass in grams / molar mass
n = 40.0g / 40.0g/mol
n = 1 mole
Volume of NaOH solution (v) = 2.5 L
Concentration of NaOH solution (c) = ?
Since concentration (c) is obtained by dividing the amount of solute dissolved by the volume of solvent, hence
c = n / v
c = 1 mole / 2.5 L
c = 0.4 mol/L (Concentration in mol/L is the same as Molarity, M)
Thus, the concentration of a solution of a 40.0 g of NaOH in 2.5 L of solution is 0.4 mol/L or 0.4M
