Your answer would be, 
Formula: Molarity (M) = Number of moles of solute/Solutions volume Liters

0.009(50) = .45 gm dissolved in 50 ml H2o
= 0.20(50) = 10 gm





Hope that helps!!!

Chemistry help please! I just need to make sure the answers correct.... Thank you!

1. At constant tempaerature and pressure, 3 tablets produce 600cm^3 of gas
Thus calculating for 1 tablet that produces 600 / 3 = 200 cm^3
So now two tablets produce 200 x 2 = 400 cm^3
2. We have the equation PV = nRT, n being the number of moles
Pressure P = 1,000 kPa
Volume V = 3 L
R = 8.31 L kPa/mol-K
Temperature T = 298 K
n = PV / RT = (1000 x 3) / (8.31 x 298) = 3000 / 2476.38 = 1.21 moles
Number of moles = 1.21 moles.

The reaction shown below occurs in the blood between hemoglobin (Hb) and oxygen.
OlgaM077 [116]

Answer:

A, B, C

Explanation:

Notice that this reaction involves double arrows, meaning this represents an equilibrium reaction in which we observe a forward reaction (combination of hemoglobin and oxygen) and a reverse reaction (decomposition of the oxyhemoglobin complex).

Upon inhalation of oxygen, it accesses the blood of a person and binds to hemoglobin, so the following reaction proceeds to the right.

Similarly, the opposite process takes place in muscles, oxyhemoglobin is decomposed back into hemoglobin and oxygen.

The equilibrium constant reaction is relatively high, since at standard conditions, this is a spontaneous reaction, hemoglobin combines with oxygen without any additional external source of energy.

Explain what atom is used as a reference when determining how many atoms are in a mole
Whitepunk [10]

Answer: Ok so the MOLE (mol) is a unit of measurement representing the amount of a substance that contains the same number of atoms as there are molecules in exactly 12 grams of carbon-12 (i.e., 6022X1023).

Explanation: And that's how it goes, I hope you understood it well!

Best regards (Pr. El Haji)
