Answer:
Hence, 15.99 g of solid Aluminum Sulfate should be added in 250 mL of Volumetric flask.
Explanation:
To make 0.187 M of Aluminum Sulfate solution in a 250 mL (0.250 L) Volumetric flask
The molar mass of Aluminum Sulfate = 342.15 g/mol
Using the molarity formula:-
Molarity = Number of moles/Volume of solution in a liter
Number of moles = Given weight/ molar mass
Molarity = (Given weight/ molar mass)/Volume of solution in liter
0.187 M = (Given weight/342.15 g/mol)/0.250 L
Given weight = 15.99 g
Answer: The amount of water produced is 9.3 grams
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
mass of reactants = mass of methane + mass of oxygen = 22.5 g + 35.7 g = 58.2 g
mass of products = mass of carbon dioxide + mass of water = 48.9 g + mass of water
48.9 g + mass of water = 58.2 g
mass of water = 9.3 g
Answer:The outer core of the Earth contains a lot of iron in a molten state. As the Earth spins this molten iron moves and creates the Earth's magnetic field. The Earth behaves as if there is a huge bar magnet at its centre. The shape of the field around the Earth is very similar to the field around a bar magnet

Answer:
Hm creo que es La carcasa es de titanio y la batería está compuesta de acumuladores de litio y yodo, que pueden durar cerca de diez años. Los electrodos que lo componen pueden ser de distintos tipos, pero sus puntas, que no están aisladas, son de platino, y el número de los mismos dependerá de las necesidades de cada paciente
Explanation:
Hello there!
How is density different from weight and mass you say? It's simple!
1. Unlike weight, density is composed of mass and volume.
2. By dividing the mass over the volume, you can determine an object's density, while weight is the product of mass and gravity.
Hope this helps :) if so, can I get Brainliest?
