If 162.35 g aluminum hydroxide are dissolved in 6750 mL of solution, the concentration of the solution is 0.308M
<h3>How to calculate concentration?</h3>
The concentration of a solution can be calculated using the following formula:
Molarity = no of moles ÷ volume (L)
However, the number of moles in 162.35g of Al(OH)3 must be calculated as follows:
Molar mass of Al(OH)3 = 78g/mol
no of moles = 162.35g ÷ 78mol
no of moles = 2.08mol
Molarity = 2.08mol ÷ 6.75L
Molarity = 0.308M
Therefore, if 162.35 g aluminum hydroxide are dissolved in 6750 mL of solution, the concentration of the solution is 0.308M.

Answer:
The answer is 144g
Explanation:
This is because oxygen gas (O2) has a mass of 32g and you have 4.5 moles of O2, so you have to multiply 4.5 and 32.

Answer:
The sun provides what almost everything on Earth needs to go—energy, or heat. Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds.

hello your question is incomplete attached below is the complete question
answer :
Fe2O3 = 159 g/mol
CO = 28.01 g/mol
Fe = 55.85 g/mol
CO2 = 44.01 g/mol
Explanation:
Fe = 55.85 g/mol
O = 16.0 g/mol
hence the molar mass of Fe2O3 = 2(55.85) + 3(16) = 159 g/mol
C = 12.01 g/mol
O = 16.0 g/mol
hence the molar mass of CO = 28.01 g/mol
Fe = 55.85 g/mol
C = 12.01 g/mol
O = 16.0 g/mol
hence the molar mass of CO2 = 12.01 + 2(16) = 44.01 g/mol
