Answer:
There are 120 possible ways.To calculate the number of permutations here, where order is important and repetition is not allowed, we use the following formula:Number of permutations = n! / (n - r)! = 5!/0! = 12345 / 1 (note: "!" means "factorial" and 0! equals 1) = 120/1 = 120.For a complete list see below. Let a,b,c,d & e represent the 5 players and their order determine their position:{a,b,c,d,e}
Explanation:
Manganese since the atomic number is 25
Answer:
THE MOLAR MASS OF XCL2 IS 400 g/mol
THE MOLAR MASS OF YCL2 IS 250 g/mol.
Explanation:
We calculate the molar mass of XCL2 and YCL2 by bringing to mind the formula for molar mass when mass and amount or number of moles of the substance is given.
Number of moles = mass / molar mass
Molar mass = mass / number of moles.
For XCL2,
mass = 100 g
number of mole = 0.25 mol
So therefore, molar mass = mass / number of moles
Molar mass = 100 g / 0.25 mol
Molar mass = 400 g/mol.
For YCL2,
mass = 125 g
number of mole = 0.50 mol
Molar mass = 125 g / 0.50 mol
Molar mass = 250 g/mol.
So therefore, the molar mass of XCL2 and YCL2 IS 400 g/mol and 250 g/mol respectively.
