1 mole of a pure substance has a mass equal to its molecular mass expressed in grams.
This is known as the molar mass, M, and has the units g mol-1
So 2 moles of a substance would have a mass = 2 x molar mass
3 moles of a substance would have a mass = 3 x molar mass etc
This leads to the formula: mass = moles x molar mass
If we let:
m = mass of substance in grams,
n = moles of pure substance,
M = molar mass of the pure substance in g mol-1
we can write the equation: m = n x M
This equation can be rearranged to give the following:
n = m ÷ M (moles = mass ÷ molar mass)
M = m ÷ n (molar mass = mass ÷ moles)

Answer:
Silicon
Explanation:
One of the most similar elements to carbon on periodic table is silicon. Several compounds formed between carbon or silicon and other elements are identical.
Carbon is an element found in life forms as a building block while silicon is a building block of machine components such as semiconductors
Silicon is an element that can sustain bonds, similar to carbon bonds and it is situated directly under carbon on the periodic table
I believe the answer is F
