Answer:
100
Explanation:
Step 1: Subtract 50 by 300 to find the total mass of the marbles
300 - 50 = 250
Not hard, right?
Step 2: Divide 250 by 2.5
250 ÷ 2.5 = 100
And... 100 is your answer :)
Hope this helps :)

Answer: C) Tetrahedral
Explanation:
The number of electron pairs is 4 that means the hybridization will be 
but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.
Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be 
.
Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be .
Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be 
.
Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be 
.
Snow is the result of moisture and low temperatures colliding; when they collide, they become tiny ice crystals. When ice crystals stick to one another, they become snowflakes. Snow is important to the water cycle because when they precipitate to the earth, they start to melt on surfaces warmer than themselves. The melted result becomes water, and when the water either seeps into the ground or flows into a source of water nearby, the water cycle's process repeats all over again.

The mass of the salt converted into moles divided by the liters of water in a solution would give the Molarity (M) or concentration of the solution. The simplest way to change the solution would be to change the amount of solute or solvent in a solution.
