Answer:
852g
Explanation:
From the question given, we obtained the following information:
Molarity = 3M
Volume = 2L
Mole =?
First, we need to find the number of mole of Na2SO4 present in 2L of the solution. This is achieved by doing the following:
Molarity = mole /Volume
Mole = Molarity x Volume
Mole = 3 x 2 = 6moles
Next, we'll find the molar mass of Na2SO4, as illustrated below:
Molar Mass of Na2SO4 = (23x2)+32+(16x4) = 46 + 32 + 64 = 142g/mol
Recall:
Number of mole = Mass /Molar Mass
Mass = number of mole x molar Mass
Mass = 6 x 142 = 852g
Communities is all the populations living in an ecosystem at the same time. A predator-prey relationship is an organism that eats another organism.
Answer:
The answer is "670.176 km".
Explanation:
Volume of the occupies of one M & M= 0.5 \ cm^3\\\\
M&M 1 mole
Calculating volume of M& M mole
Calculating the cube mole
Therefore 18 tractor trailers wouldn't be sufficient.
Answer:
Homogeneous means composed of parts of different kinds; having widely different elements or components.
Explanation:
2Fe + 3Cl₂ ---> 2FeCl₃
4.4mol of Fe, you have a 2:3 ratio of Fe to Cl₂ so divide 4.4/2 = 2.2 and multiply by three 2.2 x 3 = 6.6mol of Cl₂
hope that helps :)
